Question

Mayce worked at a summer camp where she earned $20 plus $7 an hour each week, the amount of money she earned each week, E, could be represented by E = 20 + 7h for h hours worked. If Mayce could not work more than 20 hours each week, what is a reasonable domain and range for this situation?

Answer 1

where

E = amount of money earn each week

E = 20 + 7h

h = hours worked

E = 20 + 7h

If he could not work more than 20 hours each week the domain(input) will be

domain = 1, 2, 3, 4, 5 , 6, 7, 8........................20

The range is the output values

E = 20 + 7(1)= 27

E = 20 + 7(2)=34

E = 20 + 7(3)= 41

E = 20 + 7(4)=48

E = 20 + 7(5)= 55

E = 20 + 7(6)=62

E = 20 + 7(7)= 69

E = 20 + 7(8)=76

E = 20 + 7(9)=83

...........................E = 20 + 7(20)= 160
