Answer 1

The painters hourly rate is $35.00

no matter how much hours, each hour costs $35, as seen (35h)

hope this helps

Answer 2

For h hours of work, the cost, c, is 35h + 60. 35 is multiplied by h, the number of hours, so 35 is an hourly fee. 60 is a fixed fee.

Let's look at each option.

A. The domain of this function represents the total cost for a job.

The domain is the set of values you input into h, the number of hour, not the cost. A is false.

B. h is a function of c .

False. It's the opposite. The function is written as c being a function of h.

C. The painter charges a $35 service fee in addition to an hourly rate.

We saw earlier that the fixed fee, or service fee, is $60. $35 is the hourly fee since in the function, it is 35 that is multiplied by the number of hours. C. is false.

D. The painters hourly rate is $35.00

True. Since in the function, the number of hours is multiplied by 35, 35 is the hourly rate.
