Candace drives a total of 48 miles each day to get to work and back home. She works 5 days a week. Her car gets 21 miles per gallon of gas. About how many gallons does she need to drive to work and back home each week?

11.43 gallons used exactly per week asuming not changes in schedule or any other reasons to drive and that a one way trip is 24 miles.

Step-by-step explanation:

48 as total for two trips

five of these need to be done, so 240 miles a week assuming no other reason to drive

240 / 21 = 10 with remainder 30

so 11 and remainder 9

9/21 = nearly .43 gallons, which means as a minimum she shouldn't go below 11.5 and better yet 12 gallons.
