3 gal = 12 quarts

Each scoop makes 3 quarts

12 quarts / 3 quarts per scoop = 4 scoops

joseph is planning a 2500 mile cross-country trip in his new sports utility vehicle. he uses the following information about his vehicle to figure out how much money to budget for gas:

. the vehicle has a 15 gallon tank

. the vehicle gets 25 miles per gallon

if the gasoline costs $2.99 a gallon, how much gas money will joseph need for his trip? (note:each time he stops for gas, joseph fills the tank completely.)

15 gal/tank x 25 mpg = 375 miles/tank

2500 mi / 375 per tank = 6.67 tank fills

= 7 tank fills (Joe always fills tank)

15 gal per tank x 7 tank fills = 105 gal

105 gal x 2.99/gal = $313.95 gas expense
