Brenton’s weekly pay, P(h) , in dollars, is a function of the number of hours he works, h. He gets paid $20 per hour for the first 40 hours he works in a week. For any hours above that, he is paid overtime at $30 per hour. He is not permitted to work more than 60 hours in a week.

Which set describes the domain of P(h)?

{h| 0 ≤ h ≤ 40}
{h| 0 ≤ h ≤ 60}
{P(h)| 0 ≤ P(h) ≤ 1,400}
{P(h)| 0 ≤ P(h) ≤ 1,800}

(this is as much as i can provide for the problem, its all that's shown)

The domain is the set of values that he may assume. It is given in the problem statement as h ≤ 60, so answer (B) is the selection of choice.

Hope this helps!

Answer:

[tex]0\leq h\leq 60[/tex]

Step-by-step explanation:

According to the problem, [tex]h[/tex] refers to hours wored and [tex]P(h)[/tex] refers to the money earned.

Notice that Brenton has a limit of hours, he can't work more than 60 hours, which means

[tex]h\leq 60[/tex]

Now, as function of time, [tex]h[/tex] can't be negative, that means this variable is defined by the interval

[tex]0\leq h\leq 60[/tex]

Notice that [tex]h[/tex] is the independent variable, which means the interval we found represents the domain of the function.

Therefore, the answer is [tex]0\leq h\leq 60[/tex]
