Question

Janet filled up her 20 gallon gas tank for $58.60. Afterwards she realized the gas across the street was $2.58. How much per gallon could Janet have saved had she filled up across the street?

Answer 1

Janet could have saved $0.35 per gallon or $7 in total if she had filled up across the street.

Step-by-step explanation:

To find out how much per gallon Janet could have saved, we need to calculate the price difference between what she paid and the price across the street. Janet paid $58.60 for 20 gallons, which means she paid $2.93 per gallon. If the gas across the street was $2.58 per gallon, Janet could have saved $0.35 per gallon. So, if she had filled up across the street, she could have saved $7 (20 gallons x $0.35 per gallon).
