Answer 1

Let h = hours. Earnings E(h) = 10 + 15h (dollars).

Table:
- h = 1 → E = 10 + 15(1) = $25
- h = 1.5 → E = 10 + 15(1.5) = $32.50
- h = 2 → E = 10 + 15(2) = $40
- h = 2.5 → E = 10 + 15(2.5) = $47.50
- h = 3 → E = 10 + 15(3) = $55

As ordered pairs: (1,25), (1.5,32.5), (2,40), (2.5,47.5), (3,55).
