Answer:
The expression represents the price you paid per gallon is:
- Price paid per gallon =
Step-by-step 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 =
- Price paid per gallon =
- 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:
- <u>Number of dollars (d) = 8 * $7 = $56 </u>
