Question

Xin earned $66 at her job when she worked for 4 hours. Fill out the table
Hours Dollars
33
4 66
10

Answer 1

To complete the table, let's determine how many dollars Xin earned per hour.

She earned $66 for 4 hours of work:

\[
\text{Dollars per hour} = \frac{66 \text{ dollars}}{4 \text{ hours}} = 16.5 \text{ dollars/hour}
\]

Now, we can use this rate to fill in the missing values in the table.

1. For 10 hours:
\[
\text{Dollars} = 10 \text{ hours} \times 16.5 \text{ dollars/hour} = 165 \text{ dollars}
\]

2. For 1 hour (as seen through the 33 dollars entry), to determine how many hours correspond to $33:
\[
\text{Hours} = \frac{33 \text{ dollars}}{16.5 \text{ dollars/hour}} = 2 \text{ hours}
\]

So, the completed table is:

| Hours | Dollars |
|-------|---------|
| 2 | 33 |
| 4 | 66 |
| 10 | 165 |
