Answer:

Hence, his driving cost of the trip= $ 145.

Step-by-step 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.
