Question

Andrew is paid $4 per hour for the first 30 hours he works each week. he makes $5 per hour for each hour he works over 30 hours per week. in other words, total wages = fixed wages for 30 hours additional wages at $5 per hour. the amount of money that andrew earns varies depending on the number of hours above 30 hours that he works. write the function for the four inputs listed, 32, 36, 38,40. part cexplain how this real-life situation is a function. what are the function’s input, output, domain, and range?

Answer 1

W = 120 + 5(h - 30). 

 

So, if he works 35 hours, he will earn:

 

120 + 5(35 - 30) = 120 + 5(5) = 120 + 25 = $145.

 

If he works 42 hours, he will earn:

 

120 + 5(42 - 30) = 120 + 5(12) = 120 + 60 = $180.
