Piecewise function. a house painter charges $12 per hour for the first 40 hours he works, time and a half for the 10 hours after that, and double time for all hours after that. how much does he earn for a 70-hour week?

Given that a house painter charges $ 12 per hour for the first 40 hours he works, time and a half for the 10 hours after that, and double time for all hours after that, to determine how much does he earn for a 70-hour week The following calculation must be carried out, proposing a linear function:

Therefore, the house painter earns $ 1,140 for a 70-hour week.

First 40 hours rate = $12 per hour.

Next 10 hours charge ( Upto 50 hours) = A half of $12 that is $6 per hour.

And after next 10 hours chrges ( More than 50 hours) = 2 times of initial rate, that is 2*12 = $24 per hours.

Let us take variale x for number of hours and f(x) is the function for total earning for x hours.

So, we can setup a piecewise function as

Therefore,

70 hours can be divided into = 40 hours + 10 hours + 20 hours.

Total earning of 70-hour week =  12* 40 hours  + 6 * 10 hours + 24*20 hours

= 480 + 60 + 480

= $1020.

Therefore, he earn $1020 for a 70-hour week.

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
