Question

The weekly pay for working a job is given by the function P(h) = 15h, where "h" is the number of hours worked. The company restricts workers to a maximum of 40 hours per week. The tax on the pay is given by the function T(P) = 0.18P, where "P" is the weekly pay. What is the BEST description of the domain for the tax function T(P)? A) {0, 1, 2, 3, ..., 40} B) {0, 15, 30, 45, ..., 600} C) {any nonnegative real number ≤ 40} D) {any nonnegative real number ≤ 600}

Answer 1

Either B or D.

Explanation:

I consider both options valid. It all depends on how the employer is keeping track of time, ie if the pay "ticks" every 60 minutes, or an employee is allowed to clock in half hours.

Will I be able to work 30 and a half hour for example? If I'm allowed to, D.

If I have to work multiple of 60 minutes, B.

Answer 2

The answer is D
