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.
