Question

A car rental company offers two plans for renting a car.

Answer 1

Answer:

More than 375 miles.

Step-by-step explanation:

Let x represent number of miles.

We have been given that according to plan A, the company charges 20 dollars per day and 8 cents per mile.

The cost of driving a car for x miles would be $0.08x$.

The total cost of driving a car for x miles would be $0.08x+20$.

To find the number of miles, we can represent our given information in an inequality, where cost of plan A is greater than plan B as:

$0.08x+20>50$

$0.08x+20-20>50-20$

$0.08x>30$

$\frac{0.08x}{0.08}>\frac{30}{0.08}$

$x>375$

Therefore, we should drive more than 375 miles for plan B to save us money.
