Jacks car averages 31.5 miles on the highway per gallon. if his fuel tank holds 13.2 gallons and it is 3/4 full then how far can he travel on the highway on his tank of gas?

311.85 miles

Step-by-step explanation:

Fuel tank holds 13.2 gallons and is 3/4 full, therefor the actual amount of fuel Jack has=(3/4)×13.2 gallons=9.9 gallons

The car travels 31.5 miles per gallon, 31.5 miles= 1 gallon

Then 9.9 gallons will take him for= (31.5×9.9) miles= 311.85 miles

i would say c is the best answer, hope it's right!

good luck! =)
