Is .80 cents same as 80 cents?

No.  \n\n.80 cents = 8/10 of one cent\n\nThey probably made a typo on the ballot ... they probably meant to say $0.80 (which, as I'm sure you know, means 80 cents), but halfway in between (i.e. after writing (0.80)) they decided to write "cents" ... therefore ending up with "0.80 cents" rather than "$0.80".\n\nAs this real-life example you stumbled across illustrates so well, there is a scarily high degree of math illiteracy out there!  It's frightening to think that the people writing up the ballots for a TAX couldn't even get the basic math correct!\n\n~ ♥ ~

what you did was find 80% of 40\n\nSince it is 80% OFF, you have to subtract that from 40\n\n40 - 32 = 8\n\nyour other option is to change the percentage.  Since it is 80% off - what you pay is 20%.  20% of 40 = 8

the first three questions are answered as follows\n~ = means repeating decimal\n#1     $75 - (75 x .333~) = $50\n#2     $150 - (150 x .5) = $75\n#3     $750 x .1 = $75\n\nthe easiest way to the the additional problems you have add is as follows\n\n#1    80 x .2 = 16\n#2    50 x .5 = 25\n#3    40 x .1 = 4\n#4    68 x .25 = 17

It depends where your coin is from. If it is from the United States, try www.pcgs.com. They have a pricing guide, updated daily, and information to help you determine which coin you have. Good luck!

aren't they the same amount?

I'd like to tell you a couple of tricks for getting ABOUT the right answer, which is often all you need, for instance when you're buying something and want to guard against a major cashier's error.\nMultiplying two numbers: Try to simplify the problem. Say it's 15 cans of something at 39 cents a can. Well 39 is pretty close to 40, so you get 15*40=$6.00. Or if you want it exactly, 15*40=$6.00 but subtract 15 cents because you added it when you simplified. $6.00 - $0.15 = $5.85. That's a lot easier than mentally multiplying 15 by 39.\nOften there seems to be no way to simplify the problem. Like 34 * $0.57. Well see what happens if you decrease one a little and increase the other by the same percentage. Say we take 34 down to 30, that's a little more than 10% less. Then what's a little more than 10% of 57? About 7. So we add 7 to 57, and we have 30 * $.64 = $19.20. The actual answer is $19.38. Again, not too bad. Or a 3-digit number: Try $3.79 * 18. OK, lets put $3.79 up to $4.00, about a 5% increase. Then take about 5% off 18 and it's 17. $4.00 * 17 = $68.00, compared to the exact answer of $68.22. \nHow about when you have a bunch of different items in the supermarket cart and you want the approximate total? Just keep track of the dollars and remember the cents as simple fractions of a dollar. So if you have these items: $1.39, $3.75, $2.19, $7.63, you say 1 & 1/3 plus 3 & 3/4 is 5 & a little; plus 2 & a little is 7 & 1/2; plus 7 & 1/2 is 15. The actual total is $14.96. Again, not too bad, although it won't always be this close. I hope you can use these. It gets easier with practice.

1:1.95\n\nthe " : " is a ratio meaning, from math class.\n\nLike a 1:1 ratio...or a 1 to 1 ratio.\n\n1:1.95 means 1 sterling pound is = to 1.95 in US money.\n\nSo that means 7.50 sterlings x 1.95 US = US price

CDN weighs 2.6 grams. USD weighs 2.48 grams. Not sure about any other "cents", though...\n\n150 pennies would weight 390 grams CDN and 372 grams USD.

We need a certain amount of each kind of candy.\n\nCall the amount (in pounds) of the 50 cent candy X. Call the amount (in pounds) of the 75 cent candy Y.\n\nTo get 80 pounds of the mixture, X + Y = 80.\n\nThe candy mixture has a total value of:\n\n80 pounds * (55 cents per pound) = $44.\n\nThe value of the 50 cent candy used is 0.50X. The value of the 75 cent candy used is 0.75Y.\n\nTo have the values add up, 0.50X + 0.75Y = 44.\n\nHere is the system of equations:\n\nX + Y = 80\n0.50X + 0.75Y = 44\n\nThere are many ways to solve systems. I'll use substitution here:\n\nX + Y = 80\nY = 80 - X\n\n0.50X + 0.75Y = 44\n0.50X + 0.75(80 - X) = 44\n0.50X + 60 - 0.75X = 44\n-0.25X = -16\nX = 64\nY = 80 - X\nY = 16\n\nUse 64 pounds of the 50 cent candy, and 16 pounds of the 75 cent candy.\n\nCheck:\n\nClearly, 64 + 16 = 80 pounds.\n\nThe 64 pounds of 50 cent candy costs 32 dollars. The 16 pounds of 75 cent candy costs 12 dollars.\n\nThe total value of the 80 pounds of candy is 44 dollars.\n\n44 dollars/80 pounds = 55 cents per pound\n\nIt works!

Hey, if you've got about 80 Euros, you can get about 100 dollars for it ... is that a deal or what?  That's 20 more than you started with!

OK, when you change a percent to a fraction, remember that a percent is the same as a hundredth.  So 80% = 80/100 or 4/5, and 87.5% = 87.5/100 or 7/8.\n\nIt looks like the other numbers here are already fractions.

A 100% mark up means you double the price,so 8.50+8.50=17.00,  to get 10 percent, you move the decimal 1 space left, so that gets you .850 or, 85cents. total,$17.85
