tax = .50 cents a gal\noil companies get .09 a gal\n\nwho gets the 2.00? the station?\n\nHELP

The station makes very little on a gallon of gas.  Thats why most stations sell other things besides gas.  The truck driver, (the distributor, also called a jobber make some)  The refinery probably makes the most, and whoever they buy the oil from.

3 shirts x $18.99 each = $56.97\n$75 - $56.97 = $18.03 left over...\n\nIf we get more complicated, and include tax, it depends on where you live...  I'm going to use the example living in ny, since thats where i live...  I just looked it up its a 8.625% rate\n\nsoo..\n\nTake the $56.97 total x 8.625% = $4.9136625 sales tax\n$4.9136625 + the $56.97 = $61.8836625, which rounded off to nearest penny = $61.88 being the total price\n\nTake the original $75 - $61.88 = $13.12 left over...

something is wrong in the way the problem is stated\nboth the answers are wrong, according to me.\nif you differentiate -19800-50.01x  you will get -50.01 and that cannot be equated to zero

Three men rent a room for $30.00. ($10.00 each)  When they got to the room there was no heat.  They called the man at the front desk who sent up a $5.00 refund.  They couldn't evenly split the five so they each took a dollar and gave the bellhop a $2.00 tip. Now the three men ended up paying $9.00 each because they all took a dollar back from the five. (9 x 3 = 27) Plus the $2.00 tip to the bellhop. (27 + 2 = 29)  What happened to the last dollar?\nI LIKE THIS ONE TOO !!

To change "6 %" to a decimal, move it over two places not one.\n6 % = .06\n2.1 % = .021\n(If you forget, remember 10 % is one tenth or .10\nbut 1 % is one hundredth or .01)\n\nMultiply price 229 by .06 to get sales tax.\nMultiply price 130,000 by .021 to get property tax.\n\nAnother Trick: If you don't want just the tax by itself, but the final price including the tax added in, multiply the original price by 1.06 or 1.021

Total = price + price * tax rate = price (1+rate)\n\nSolve for price.

You have to bear in mind that the drinks were not actually $27 dollars, it was $25.  Just because you gave them a dollar each back, they ASSUMED it was $27.\nEven though they had paid $27, you still had to pay their bill of $25 which would leave you the $2.....\nthe missing $1, is therefore, not a missing dollar....!

~Let's see.  We work now until late may before we make a nickel for ourselves (duh, the rest going for taxes)  You're right.  50% is too much.  Let's keep it at our 40.5%.  Oops.  Forgot sales tax, tobacco tax, liquor tax, gas tax, ad nausuem.  We're paying close to 60%.  Bring on the warlords.  Sounds cheaper.

There is no missing dollar. You calculations are deceptive. The manager has his 25, the guys each have one and the bellhop has 2. 25+1+1+1+2=30\nAdide from that the guys haven't paid $9 each, they just think they did. They really paid less, they just didn't get all they deserved back, so in their minds they paid 9 and the manager has the other 3\nSo I'm going to assume the whole point of the (3x9)+2 is to cause confusion and the answer is that is irrelavent because they didnt pay 9 each.

The $2 should be subtracted from the $27, not added to it -- since they were overcharged by $5, the room actually cost $25.\n\nThey ending up paying $27, $25 for the room and $2 to the bellhop. That $27 plus the $3 refund is the original $30

game is marked 320.\n\n at 30% off, if i buy it i will end up paying 320/100 x 70 = 224\n\nso the discount is 320-224 = 96\n\nnow , 96 is 48% of the cost price.\n\n so the cost price is 96/48 x 100 =200\n\n so the cost price is 200 and the selling price after 30%  off is 224\n\n so, the profit is 224-200 = 24 dollars\n\n in percentage the profit is 224/200 x 100 = 112\n\n hence the profit is 12 %\n\n\n do learn how it;s done . the key is to understand the question and work it systematically. \n\n all the bets with your work\n\n study hard now . dont live to regret it \n\n God bless!

So where's that starting point?  Either we start (yesterday) with Mary having $785.63 we subtract $57. and $125. for 603.63.  Then we add $57.25 for a total of 660.88 (B) \nOR\nwe start we $785.63 (today) anb subtract $57. and $125 for $603.63 (C).  The $57.25 doesn't matter cause Mary did that yesterday....

Uhm you are vague by saying "at least $30". Hence, it is impossible to figure this out. You did not say "exactly $30".

A) Gasoline costs $2.02 for 1 gallon. We want to know how much 12 gallons of gasoline costs.\nx = cost of 12 gallons of gasoline\nx / 12 gallons = $2.02 / 1 gallon --- Cross-multiply...\n(1)(x) = (12)($2.02) --- Multiply...\nx = $24.24\nANSWER: The cost of 12 gallons of gasoline is $24.24 when one gallon of gasoline costs $2.02.\n\nB) Mr. Jones starts with $2,589.36 in his checking account. He writes checks for $689.00, $107.25, and $23.69. We want to know the remaining balance in his account.\nx = amount remaining in Mr. Jones' account\nx + $689.00 + $107.25 + $27.69 = $2,589.36 --- Combine the dollar amounts on the left side...\nx + $823.94 = $2,589.36 --- Subtract $823.94 from each side...\nx = $1,765.42\nANSWER: Mr. Jones has $1,765.42 remaining in his checking account.\n\nC) A 12 oz. can of soda costs (assuming you meant) $0.65. We want to know the cost of 1 ounce of soda.\nx = cost of 1 oz. of soda\nx / 1 oz = $0.65 / 12 oz --- Cross-multiply...\n12x = $0.65 --- Divide both sides by 12...\nx ≈ $0.05\nANSWER: An ounce of soda costs $0.05 when 12 ounces of soda costs $0.65.\n**Note: If you really meant that the soda cost $65.00 instead of 65 cents, then the price for an ounce of soda is $5.42 instead of a nickel.

The waitress calculation is wrong...\n\nYou me and Sally gave the waitress $10 each for a total of $30.\n\nThe waitress gave back $5\n\nWe gave the waitress back $2.\n\nTherefore, the waitress has $30 - $5 + $2 = $27
