What is a linear equation?

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. When this equation is graphed, it always results in a straight line."

Given, Donald's car gets about 30 miles per gallon.

Donald drive on 9.2 gallons of gas.

Therefore, total distance that Donald can go with the given gas is

= mileage of the car × total amount of gas

= 30 × 9.2 miles

= 276 miles

Again, cost of gas per gallon is $3.15.

The total cost

= total gallons of gas used × cost of gas per gallon

= $(9.2 × 3.15)

= $28.98
