Respuesta :

We know that Linda earns $12.50 an hour.

Let's find the rate of change of the graph to find Tony's earning ratio.

[tex]r=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let's use the points (0,0) and (4,40).

[tex]r=\frac{40-0}{4-0}=\frac{40}{4}=10[/tex]

This means Tony earns $10 an hour.

Then, we divide the earnings

[tex]\frac{12.50}{10}=1.25[/tex]

Hence, Linda earns 1.25 times as much per hour as Tony.
