Stephanie earns $1.5 per hour more than what Marco earns.

Linear equation

Linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the y intercept.

Let w represent the wages after h hours.

From the table using the points:

  • (15, 157.5) and (24, 252)

The rate of change (m) for Stephanie is:

  • [tex]m=\frac{y_2-y_1}{x_2-x_1} =\frac{252-157.5}{24-15} =10.5[/tex]

This means that Stephanie earn $10.5 per hour.

From the equation: w = 9h, Marco earns $9 per hour

Hence, Stephanie earns $1.5 per hour more than what Marco earns.
