The table below shows the amount of money Kyleigh earned after x hours of work. Hours Income 4 $61.00 8 $122.00 12 $183.00 16 $244.00 Who earned more money per hour at their job?

Answer 1

To determine who earned more money per hour at their job, we can calculate the hourly wage for both Anne and Kyleigh.

For Anne, the equation given is:
\[ y = 7.5x \]
This means that for each hour of work (x), Anne earns $7.50.

For Kyleigh, we can find her hourly wage using the data from the table. Let's calculate her earnings per hour based on the provided information:

- For 4 hours: $61.00 / 4 hours = $15.25 per hour
- For 8 hours: $122.00 / 8 hours = $15.25 per hour
- For 12 hours: $183.00 / 12 hours = $15.25 per hour
- For 16 hours: $244.00 / 16 hours = $15.25 per hour

Kyleigh consistently earned $15.25 per hour.

Now, comparing the hourly wages:
- Anne: $7.50 per hour
- Kyleigh: $15.25 per hour

Kyleigh earned more money per hour at her job.
