Question

A family is planning a three-week vacation for which they will drive across the country. They have a van that gets 12 miles per gallon, and they have a sedan that gets 32 miles per gallon. How much more will they pay for gasoline if they take the van? (Assume that the family will drive 3200 miles and that gas costs $3.60 a gallon. How much more (in dollars) will they pay for gasoline if they take the van?

Answer 1

3200/12=266.66 gallons
3200/32=100 gallons

266.66 X 3.60= $960
100 X 3.60 = $360

$960 - $360 = $600
