Answer:
input is your hours
output is your money
domain is all numbers greater than/equal to 0
range is any number greater than/equal to the amount of money you make per hr
Andrew’s total wages are a function of the number of hours he works. The input of this function is the total number of hours worked. The output is the total wages earned.
The domain is the number of hours that Andrew can work in a week. A week has 168 hours. He works for 30 hours regularly. So, the domain is D = {30, 31, 32, … , 168}.
Of course, it is unrealistic to expect Andrew to work 24 hours a day for an entire week. 168 simply represents the total possible hours to work.
The range is the money Andrew can make working his usual 30 hours plus any extra hours at $5 per hour: R = {120, 125, 130, ... , 810}.
