(Due in 20 minutes!)
 1. Jack works after school. Each day he earns a set amount, plus an hourly wage. Write a linear function f Jack can use to determine his pay. 
 Hours 1, 1.5, 2, 2.5, 3 
 Pay 18, 23, 28, 33, 38 
 f(x) = 10x + 8 
 2. I need to know which is a reasonable domain for how many hours Jack can work after school each day 
 A. 0 < x < 6 
 B. 0 < x < 24 
 C. 0 < x < 68 
 D. 0 < x < 248 
 3. Last part of this problem is to assume Jack works 4.5 hours. Use your function from question 1 to find how much he gets paid.
