C. 15.4 gallons
D. 7.9 gallons

Answer 1

Marvin needed approximately 14.28 gallons of gas last week.

Step-by-step explanation:

To find out how much gas Marvin needed last week, we can set up an equation using the given information. Let x represent the amount of gas Marvin needed last week.

Marvin needed 163.1% more gas this week than last week, which means he needed 1.631 times the amount he needed last week. So, we can set up the equation: 1.631x = 23.3

To solve for x, we divide both sides of the equation by 1.631: x = 23.3 / 1.631 ≅ 14.28

Therefore, Marvin needed approximately 14.28 gallons of gas last week.
