A rental car company charges a base fee of [tex]$\$[/tex]40[tex]$ plus $[/tex]\[tex]$0.25$[/tex] per mile for the first 100 miles the car is driven. The company charges the same base fee plus a reduced price of [tex]$\$[/tex]0.18[tex]$ per mile for cars driven over 100 miles. The piecewise function below represents the different amounts the company charges.

If someone drives their rental car 150 miles, how much will they owe the rental company?

A. $[/tex]\[tex]$37.50$[/tex]

B. [tex]$\$[/tex]77.50[tex]$

C. $[/tex]\[tex]$67.00$[/tex]

D. [tex]$\$[/tex]27.00$



Answer :

Let's solve this step-by-step based on the information provided.

1. Understanding the Problem:
- The base fee for renting the car is [tex]$\$[/tex]40[tex]$. - For the first 100 miles driven, the cost is $[/tex]\[tex]$0.25$[/tex] per mile.
- For any miles driven over 100 miles, the cost is [tex]$\$[/tex]0.18[tex]$ per mile including the base fee. 2. Given Data: - The car is driven for 150 miles. 3. Calculate the Cost for the First 100 Miles: - The cost for the first 100 miles can be computed as: \[ \text{Cost for first 100 miles} = 40 + (0.25 \times 100) = 40 + 25 = \$[/tex]65
\]

4. Calculate the Cost for the Additional Miles:
- Now, compute the cost for the 50 miles driven over the initial 100 miles.
[tex]\[ \text{Cost for additional 50 miles} = 0.18 \times (150 - 100) = 0.18 \times 50 = \$9 \][/tex]

5. Calculate the Total Cost:
- Add the cost for the first 100 miles to the cost for the additional 50 miles.
[tex]\[ \text{Total Cost} = 65 + 9 = \$74 \][/tex]

Thus, the total amount owed to the rental company when the car is driven for 150 miles is [tex]$\$[/tex]74[tex]$. So, the correct answer is: $[/tex][tex]$ \$[/tex] 74.00
