Expert Solution
Introduction

C++ programming language is used to answer the given question.

The formula to calculate the cost of gas for a given number of miles is calculated as follows for given miles per gallon and dollars per gallon 

Gas cost=Number of Miles*(Miles per Gallon/Dollars per Gallon)

The setprecision(decimal count) function is used to set the number of decimal places after the dot(.) in the result.

For example, setprecision(2) will display the result up to 2 decimal places.
