Answer:
Hence, his driving cost of the trip= $ 145.
Explanation:
It is given that:
Joshua is planning on 1404 miles driving trip.
His car gets an average of 36 miles per gallon.
i.e. for 36 miles his car uses 1 gallon of gas.
Hence for 1 mile his car uses=1/36 gallon of gas.
Hence, for 1404 miles his car uses=1404/36 gallon of gas
= 39 gallons.
Cos of 1 gallon of gas= $ 3.72
Cost of 39 gallons of gas=$ (3.72×39)=$ 145.08
which is approximately equal to $ 145.
Hence approximately his driving cost of the trip is $145.
