Cindy's truck get 16 miles per gallon plans to buy a hybrid car that gets 48 miles per gallon and cost 20,599 how many miles what Cindy have to drive the new car to recover her investment through money saved on gas if gas costs 3.49 per gallon

Answer 1

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
