Carol has $30 to spend on gasoline for her car. after buying 8 gallons, she has $4 left. how much did each gallon of gasoline cost?

$3.25 per gallon

Step-by-step explanation:

She had $30 and now has $4, so she spent $30- $4 = $26

With $24 she bought 8 gallons of gas.  

$26/(8 gallons) = $3.25/(1 gallon)      [ divide 26 by 8 to get the unit rate]

She spent $3.25 per gallon

The answer is 3.25 per gallon. I hope this helps!
