Question 1159134: Maxis taking a cross-country road trip. Gas prices vary as the friends travel across the US from $4 dollars per gallon on the east coast, to $3 in the mid-US, to $5 on the west coast.
b
On their way back they had more baggage in the car and spend $601 for 174 gallons of gas. Based on the same ratio as in Part (a), how many gallons of gas did they buy at each price?

The problem appears faulty as presented.

The only information we have is that 174 gallons cost $601 with the price per gallon being $3, $4, or $5.
(1) With only that information, there are numerous solutions of how many gallons were bought at each price.
(2) The average price is less than $3.50 per gallon, indicating that a huge percentage of the gallons were purchased in the central part of the country; that doesn't seem realistic.
