Question

Mylie went by the gas station to get 2.4 gallons of gas. She paid with a $10 bill and a $5 bill and received $4.68 as change. What was the cost for one gallon of gas before taxes? $4.30 $8.20 $10.32 $24.77

Answer 1

We don't know what tax percentage or amount is so we have to keep this part out.

Add to find how much she paid with.

10 + 5 = $15

Subtract to find how much she paid.

15 - 4.68 = $10.32

Divide to find the unit price.

10.32 / 2.4 = $4.30 per gallon

Best of Luck!
