Ari is starting a yard service business. He charges a flat rate of $10 plus an additional $15 per hour, regardless of the service. Create a function and use a table to determine how much Ari will make if he works for 1, 1.5, 2, 2.5, and 3 hours.(1 point)

Answer 1

To create a function for Ari's charges, we can express it mathematically. The total cost \( C \) based on the number of hours \( h \) can be defined as:

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

Where:

• \( 10 \) is the flat rate.
• \( 15h \) is the charge based on the hours worked.

Now, let's compute how much Ari will make for 1, 1.5, 2, 2.5, and 3 hours using this function.

| Hours (h) | Total Charge (C(h)) | |-----------|----------------------| | 1 | \( C(1) = 10 + 15(1) = 10 + 15 = 25 \) | | 1.5 | \( C(1.5) = 10 + 15(1.5) = 10 + 22.5 = 32.5 \) | | 2 | \( C(2) = 10 + 15(2) = 10 + 30 = 40 \) | | 2.5 | \( C(2.5) = 10 + 15(2.5) = 10 + 37.5 = 47.5 \) | | 3 | \( C(3) = 10 + 15(3) = 10 + 45 = 55 \) |

Now, let's rewrite the data in the format you provided:

1. \( (1, 25) \)
2. \( (1.5, 32.5) \)
3. \( (2, 40) \)
4. \( (2.5, 47.5) \)
5. \( (3, 55) \)

Hence, the responses for the working hours and total charges would look like this:

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

This computes how much Ari makes based on the hours he works.
