Answer 1

To create a function for Ari's yard service business, we can define the total charge \( C \) based on the number of hours worked \( h \). The charge consists of a flat rate of $10 plus $15 for each hour worked. Therefore, the function can be written as:

\[
C(h) = 10 + 15h
\]

Now, let's calculate how much Ari will make if he works for 1, 1.5, 2, 2.5, and 3 hours:

1. For \( h = 1 \):
\[
C(1) = 10 + 15 \times 1 = 10 + 15 = 25
\]

2. For \( h = 1.5 \):
\[
C(1.5) = 10 + 15 \times 1.5 = 10 + 22.5 = 32.5
\]

3. For \( h = 2 \):
\[
C(2) = 10 + 15 \times 2 = 10 + 30 = 40
\]

4. For \( h = 2.5 \):
\[
C(2.5) = 10 + 15 \times 2.5 = 10 + 37.5 = 47.5
\]

5. For \( h = 3 \):
\[
C(3) = 10 + 15 \times 3 = 10 + 45 = 55
\]

Now, we can summarize this information in a table:

| Hours Worked (h) | Total Charge (C(h)) |
|-------------------|---------------------|
| 1 | 25 |
| 1.5 | 32.5 |
| 2 | 40 |
| 2.5 | 47.5 |
| 3 | 55 |

So, the correct response matches the first set of pairs you provided:

- \( (1, 25) \)
- \( (1.5, 32.5) \)
- \( (2, 40) \)
- \( (2.5, 47.5) \)
- \( (3, 55) \)

Thus, the answer is:

**left parenthesis 1 comma 25 right parenthesis , left parenthesis 1.5 comma 32.5 right parenthesis , left parenthesis 2 comma 40 right parenthesis , left parenthesis 2.5 comma 47.5 right parenthesis , left parenthesis 3 comma 55 right parenthesis**
