Answer 1

To calculate the total cost of car washes for Mary Beth, you'll need to add the membership fee to the total cost of the car washes for each number of visits.

The total cost for a given number of visits \( v \) can be calculated using the formula:

\[
\text{Total Cost} = \text{Membership Fee} + (\text{Cost per Wash} \times v)
\]

Given:
- Membership Fee = $80.00
- Cost per Wash = $26.00

Now, let's calculate the costs for 2, 4, 5, and 8 visits.

1. **For 2 visits:**
\[
\text{Total Cost} = 80 + (26 \times 2) = 80 + 52 = 132
\]

2. **For 4 visits:**
\[
\text{Total Cost} = 80 + (26 \times 4) = 80 + 104 = 184
\]

3. **For 5 visits:**
\[
\text{Total Cost} = 80 + (26 \times 5) = 80 + 130 = 210
\]

4. **For 8 visits:**
\[
\text{Total Cost} = 80 + (26 \times 8) = 80 + 208 = 288
\]

Now, let's fill in the table:

- **Number of visits (v)**: 2, 4, 5, 8
- **Cost to get car washed (c)**: $132, $184, $210, $288

The completed table is:

| Number of visits (v) | Cost to get car washed (c) |
|-----------------------|-----------------------------|
| 2 | $132 |
| 4 | $184 |
| 5 | $210 |
| 8 | $288 |
