A car rent $175 per week plus $0.30 per mile, the rental cost for a 3 week trip of 1200 miles is $885 (using the linear equation Car rent = 175x + 0.3y)
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.
Let the car be rented for x weeks.
Let the number of miles car driven be y miles.
Car rent = 175x + 0.3y
Given that it was a 3 week trip of 1200 miles.
x = 3 weeks
y = 1200 miles
Car rent = 175 * 3 + 0.3 * 1200 = $885
