Help me with my phone plan math problem?

Let X be each additional minutes\n\nPlan A:\n           Price = .03X + 9.99\n\nPlan B:    \n           Price = .02X + 15.99\n\nPlan C:   \n           Price = .01X + 19.99 \n\nPlan A is very good when the user only uses very little minutes. If Plan A user uses an additional 350 minutes for that month, he will end up paying $20.49 for a total of 850 minutes. That has the same minutes as plan B. If he would have choose Plan B, he would only need to pay $15.99.\n\nThis goes the same with Plan B and C. Depending on how many minutes the user uses, he or she would pick a plan that fits their minute ussage. If a person pick Plan A, he will need to pay $30.99 for the same minutes as plan C which is only $19.99. \n\nPart three of this question is kinda boring\n\nPlan B will be cheaper if Plan A user uses less than 200 minutes\n       $15.99 > .03X + $9.99\n      - $9.99        - $9.99\n             $6.00 > .03X    \n               6.00/.03 > X\n                    200 > X\n\nreapeate the same steps for the rest and you'll know the numbers\n\nHALA back if your a sexy girl\njohnjing2@yahoo.com

Current revenue is $2.00 * 1,000.\n\nFor every 25 cent increase, there will be a 50 person decrease in ridership.\n\nSo, in that case revenue would be ($2.00 + $0.25x) * (1,000 - 50x).\n\nSo, I would use R = (2+0.25x)(1000-50x) = -12.5x² +150x + 2000\n\nAre you in calc or pre-calc?  Do you know if you need to determine what the maximum fare increase is before revenue starts going down?  (That's a typical type of question that's usually asked with these types of questions.)\n\n~ ♥ ~

Multiply 15% times $8.39.\nTo make it easy, think of it as 10% plus 5%.\nYou can easily find 10% of $8.39. It's $.839, which is about 84 cents.\n\nAnd 5% is half as much as 10%, so that's another 42 cents.\n\nTotal tip = 84 + 42 = 126 cents, or $1.26.\nYou could call it $1.25, but generally you should round up, or even add something ... so anywhere from $1.25 to $1.50 would be OK. If you want to send a message about disappointing service, leave less than 15%. If you want to send a message about BAD service, leave less than 10% (even MUCH less). And if you want to send a message about exceptional service, leave more than 20%.\n\nThat's a lot of different percentages that you MIGHT have to calculate. But if you can do the very simple 10% calculation, you should be able to figure out any of the above-mentioned percentages.

Call your service provider, they may be able to change your phone number.\n\nThey may charge a fee to do so, though.

go to a cell phone provider store and ask if they have these types of plans.

Do you want to know why you get your phone number?\n\nOkay, so if your phone number was actualy one number as opposed to a series of digits and it was abc-defg then it is actualy \n\n(a*10^6) + (b*10^5) + (c*10^4) + (d*10^3) + (e*10^2) + (f*10^1) + (g*10^0)\n\nwhich means you start with (a*10^6) + (b*10^5) + (c*10^4)\n\nMultiplying by 80 gives\n(8a*10^7) + (8b*10^6) + (8c*10^5)\n\nAdding 1 gives\n(8a*10^7) + (8b*10^6) + (8c*10^5) + 1\n\nMultiplying by 250 gives\n(2000a*10^7) + (2000b*10^6) + (2000c*10^5) + 250\nwhich equals (2a*10^10) + (2b*10^9) + (2c*10^8) + 250\n\nAdding the last 4 digits is the same as adding\n(d*10^3) + (e*10^2) + (f*10^1) + (g*10^0) which gives\n\n(2a*10^10) + (2b*10^9) + (2c*10^8) + (d*10^3) + (e*10^2) + (f*10^1) + (g*10^0) + 250 \n\nAdding them again gives\n(2a*10^10) + (2b*10^9) + (2c*10^8) + (2d*10^3) + (2e*10^2) + (2f*10^1) + (2g*10^0) + 250 \n\nSubtracting 250 gives\n(2a*10^10) + (2b*10^9) + (2c*10^8) + (2d*10^3) + (2e*10^2) + (2f*10^1) + (2g*10^0)\n\nAnd so dividing by 2 gives\n(a*10^6) + (b*10^5) + (c*10^4) + (d*10^3) + (e*10^2) + (f*10^1) + (g*10^0)\n\nwhich is your phone number. This process is the same if you do it backwards. (Multipy where you would divide etc...) This is the same thing as multiplying a number by 4 then dividing it by 2 then dividiing it by 2 then adding 5 then subtracting (20/4)\n\nSorry if I took the magic out of it, but that's the math that explains why it works.

HOW MANY numbers do you have their  we have 6 and 2 supps...\nsoooo.. 9.11.27.35.36.44. supps. 10.23.\nHAVE A GO WITH THEM ONES  ...\ni hope you win good luck.

The way you solve this problem is by\n\n25,000 *.057\n1,425 a year, but need only 9 months so divide by 12 and get\n118.75 a month and multiply by 9 to recieve your answer\n1068.75

Sure - What you want to do is look at how many phones were in service in the 1800's (invention of the phone) and how many phones were in use in the 1890-1900, 1901- 1910, 1911-1920 and so un up til present day.  These numbers will be on the bottom of the graph (X Axis).  On the left side (also known as the Y axis) you will put the amount of telephones in an interval - counting by 100,000's or so depending on how many phones it actually turns out to be.

The first number has to be (x+6) and the second number is (x).  There are four possible combinations: 6,0 (60); 7,1 (71); 8,2 (82); 9,3 (93).  60 plus 8 (68) does not equal 06, or 6.  71 plus 8 does not equal 17.  82 plus 8 does not equal 28.  93 plus 8 does not equal 39.\nUnfortunately, this problem is impossible.\nSorry I couldn't be of more help.

With this given data, it is not possible\n\nalthough the area is totalling to be 70 for both cases (7*10 and two pieces of 8*8 + 1*6) but with one division only, this is not possible\n\nPLEASE DO LET ME KNOW IF THERE IS SOME SOLUTION (i found it very interesting)

1)  Notice that 6^2=6*6=36; 6^3=36*6=216; everytime you multiple a power of 6 by 6, the units digit remains 6.  Now what about powers of 5?\n\n2)  If r is total minutes and the first 3 minutes is $1.00, and the rest of r costs $0.20 per minute, then the total cost would be $1.00 + $0.20(r-3) = \n1 +0.2r + 0.6 =\n1.6 + 0.2r\n\n3)  3*10^4 = 3*10,000 = 30,000, and 4*103 = 412.\nNow divide 30,000 by 412 to get their ratio, and then multply that number by 100 to convert to percent difference.\n\n4)  Not enough info - you need the height too.  If the same height, obviously the can with the larger radius\n\n5.1)  65*20% =65*0.2 = 13\n\n5.2)  Again, not enough info. From the info given, all you can say about one-half the number of people who preferred green was that it was between 0 and (65-13)/2, aka 26

Just contact your phone company and ask for an itemized account of the phone usage. They will provide all the details, as long as it's your phone.\n\nSince it's not your phone, the only legal way is to ask and have him show you the itemized bill. You could try to think of some excuse that you want to see it, but there's no way you can get it from the phone company itself. Only from him.
