Question

A rental car company charges $70.00 just to rent a car, and $50.00 for each day you keep the car.
How much would it cost to rent a car for 2 days?
Number of days (n) Cost to rent a car (c)
2 $
4
7

Answer 1

To calculate the cost to rent a car, you can use the formula:

\[
c = 70 + (50 \times n)
\]

where \( c \) is the total cost and \( n \) is the number of days rented.

1. **For 2 days**:
\[
c = 70 + (50 \times 2) = 70 + 100 = 170
\]
Therefore, the cost to rent a car for 2 days is **$170.00**.

2. **For 4 days**:
\[
c = 70 + (50 \times 4) = 70 + 200 = 270
\]
The cost to rent a car for 4 days is **$270.00**.

3. **For 7 days**:
\[
c = 70 + (50 \times 7) = 70 + 350 = 420
\]
The cost to rent a car for 7 days is **$420.00**.

Now, summarizing the costs:

| Number of days (n) | Cost to rent a car (c) |
|---------------------|-------------------------|
| 2 | $170.00 |
| 4 | $270.00 |
| 7 | $420.00 |
