Hi there! I can help you! Okay, so to find the answer for these types of questions, we have to divide the total cost on gas by the number of gallons filled in the tank. With that being said, if you do this correctly, here are your answers.

Genevieve: $3.68
Unnamed Person: $3.64

When you compare the prices, you see that 3.64 < 3.68. With this being the case, the unnamed person spent less per gallon of gas.
