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

Which set describes the domain of [tex]\(P(h)\)[/tex]?

A. [tex]\(\{h \mid 0 \leq h \leq 40\}\)[/tex]

B. [tex]\(\{h \mid 0 \leq h \leq 60\}\)[/tex]

C. [tex]\(\{P(h) \mid 0 \leq P(h) \leq 1,400\}\)[/tex]

D. [tex]\(\{P(h) \mid 0 \leq P(h) \leq 1,800\}\)[/tex]



Answer :

Let's examine the question carefully to determine the domain of Brenton's weekly pay function, [tex]$P(h)$[/tex], which is dependent on the number of hours he works, [tex]$h$[/tex].

First, we need to identify the possible range for the number of hours Brenton can work in a week. According to the problem, he can work from 0 hours to a maximum of 60 hours per week.

1. Minimum Hours:
- The smallest value for [tex]$h$[/tex] is 0. This means Brenton cannot work less than 0 hours in a week.

2. Maximum Hours:
- The largest value for [tex]$h$[/tex] is 60, as he is not permitted to work more than 60 hours in a week.

Given these constraints, the domain of [tex]$P(h)$[/tex], which represents the number of hours Brenton can work in a week, is the set of all possible hours he can work, ranging from 0 up to 60.

Among the provided options, the correct set that describes the domain of [tex]$P(h)$[/tex] is:
[tex]\[ \{ h \mid 0 \leq h \leq 60 \} \][/tex]

Therefore, the correct answer from the given choices is:
[tex]\[ \{h \mid 0 \leq h \leq 60\} \][/tex]
