You are looking into buying vehicle that is either fueled by gasoline or diesel. From published reports it seems the gas vehicle will get 29 miles per gallon while the diesel vehicle runs at 33 miles per gallon. On the flip side, gas is about $2.30 per gallon while diesel is about $2.50 per gallon. If you are going on a 500 miles trip, which vehicle is the better option?



Answer :

Step-by-step explanation:

we start with finding how many gallons of their fuel they will need for the trip:

the gas version gets 29 miles per gallon. for 500 miles that is 500/29 = 17.24137931... gallons

the diesel version gets 33 miles per gallon. for 500 miles that is 500/33 = 15.15151515... gallons.

now we multiply the needed gallons by their price.

17.24137931... gallons of gas cost

17.24137931... × 2.3 = $39.65517241...

15.15151515... gallons of diesel cost

15.15151515... × 2.5 = $37.87878788...

so, the diesel vehicle is the cheaper version for the trip.
