Question

A car company charges customers an initial charge plus a daily charge to rent cars. The initial charge is $40 and the daily charge is $35. The rental company charged Frank $180. Create an equation that can be used to find the number of days, x, that Frank rented the car.

Answer 1

Total Charge = Initial Charge + Daily Charge x Number of Days

Explanation:

Let's assume that x is the number of days that Frank rented the car.

The initial charge for the rental is $40, which is a one-time charge, so it does not depend on the number of days.

The daily charge for x days is $35 per day. Therefore, the total charge for x days can be calculated as:

Total Charge = Initial Charge + Daily Charge x Number of Days

Total Charge = $40 + $35x

We know that Frank was charged $180, so we can set the total charge equal to $180 and solve for x:

$40 + $35x = $180

Subtracting $40 from both sides gives:

$35x = $140

Dividing both sides by $35 gives:

x = 4

Therefore, Frank rented the car for 4 days.
