Linda commutes a total of 54 miles to and from work every day. She needs a new car, and good gas mileage is important to her. She’s considering two models. The first model averages 30 miles per gallon, and the second averages 27 miles per gallon. How many gallons of gas will she save in a five-day work week if she buys the first car instead of the second car?

she would save 1.1 extra gallons

Step-by-step explanation:

54 miles to work

30 miles a gallon so 1.8 gallons to get to work

27 miles a gallon so 2 gallons to get to work

30 miles car saves 5.4 miles more each day she drives to work

5.4 X  5 = 27 extra miles so 1.1 gallons she would be saving each work week

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

the correct answer is x/3+10≥32

hope this !
