Question 1037317: 2016 Current Federal gas tax is 18.4 cents per gallon of gas. My state gas tax is 19.0 cents per gallon of gas. The total tax on a gallon of gas in my state is 37.4 cents per gallon. I need an equation that can be used to tell me the total amount of tax paid whenever I fill up my vehicle. Can you provide me with such an equation?

You can put this solution on YOUR website!
x = number of gallons.
19 cents = .19 dollars
18.4 cents = .184 dollars.
37.4 cents = .374 dollars.

multiply x by .374 and you get the cost of the tax in dollars and cents.

for example, when x = 20, tax = .374 * 20 = 7.48 = 7 dollars and 48 cents.

so your formula is tax dollars = .374 * x, where x is the number of gallons you bought.
