Question

Let d be the number of dollars you spent on gas and let g be the number of gallons you purchased. Which expression represents the price you paid per gallon?

Answer 1

The expression represents the price you paid per gallon is:

• Price paid per gallon =
  `(d)/(g)`

Explanation:

To identify the expression is right, I'll show you with an example: suppose that you paid $56 buying 7 gallons of gas, now you can replace those values in the expression I gave you:

• Price paid per gallon =
  `(d)/(g)`
• Price paid per gallon =
  `(56)/(7)`
• Price paid per gallon = 8

And you can check this value by multiplying the price paid by the gallon and the number of gallons, which you obtain the number of dollars you spent:

• Number of dollars (d) = 8 * $7 = $56
