a.$22
b.$23
c.$24
d.$25

Answer 1

18/6 = 3 dollars per gallon

8 x 3 = 24

 8 gallons would cost $24

answer is C

Answer 2

Answer:

c.$24

Step-by-step explanation:

to find how much it would cost for 1 gallon, the easiest way to do that is subtract 21 from 18.

21 - 18 = 3

So, it's 3 dollars per gallon. Now that we know that we multiply it by 8 to find how much it would cost.

8 x 3 = 24

Eight gallons of gas would cost 24$ :3
