The first thing we must do for this case is to look for the linear function of the bob's earnings.
The slope is:
m = (93.60-46.80) / (6-3)
m = 15.6
Then, the linear equation is:
y = 15.6x
Therefore, we observe that Bob has more earnings per hour than Winnie because the slope of the line is higher (15.6> 11.5)
Answer:
Bob has more earnings per hour than Winnie because the slope of the line is higher (15.6> 11.5)
