Question

A contractor's total earnings from a job include a fixed amount plus an amount based on the number of hours worked. The values in the table represent the linear relationship between the number of hours worked and the contractor's total earnings in dollars.

What is the rate of change of the contractor's total earnings in dollars with respect to the number of hours worked?
$8.75 per hour worked
$9.25 per hour worked
$10.00 per hour worked
$20.00 per hour worked

To find the rate of change of the contractor's total earnings with respect to the number of hours worked, we need to determine the slope of the linear relationship between the two variables.

Looking at the values in the table, we need to find the change in total earnings for each additional hour worked.

For example, if the total earnings change from $50 to $59 when the number of hours worked changes from 5 to 6, the change in total earnings for 1 additional hour worked is $59 - $50 = $9.

From the values in the table, we can see that for each additional hour worked, the total earnings increase by $10. Therefore, the rate of change of the contractor's total earnings in dollars with respect to the number of hours worked is $10 per hour worked.

So the answer is $10.00 per hour worked.
