so the questioon is asking for how many gass refils she would have saved so we want to find how many gas refils equals to the cost of the car so 3.49x=20,599 divide both sides by 3.49 and get x=miles=5902 gas refils each gass refil fo r the truck is every 16 mile so 16 times 5902 or 94432 miles
Cindy would need to drive approximately 141,000 miles in her new hybrid car to recover her investment of $20,599 through savings on gas. By calculating the cost per mile for both her truck and the hybrid car, we found her savings per mile to be about $0.145. This calculation shows how fuel efficiency can significantly impact long-term savings with a more economical vehicle.
