Answer :
The rate of change of the contractor's total earnings in dollars with respect to the number of hours worked is A) $8.75 per hour worked.
To calculate the per hour worked we have to subtract the total earnings from 35 to 40 hour and divide it by gap.
Rate of change = (370 - 326.25)/(40 - 35)
= 43.75/5
= 8.75 per hour worked
We can see the difference between each earning is $43.75 and there is gap of 5 in every section, so earnings are uniform.
The definition of labor compensation per hour worked is the employee's total remuneration in national currency divided by the employee's total number of hours worked.
The total of an employee's gross wages, salary, and social security contributions constitutes their compensation. Annual growth rates and indexes are used to measure this metric.
