Answer:
Explanation:
Amount of money earned by John for each shift he works at the bookstore is represented by the function,
f(h) = 10h
Where f(h) = Amount of money earned in dollars
h = number of hours worked by John
1). For h = 1 hour
f(1) = 10 × 1
= $10
2). For h = 2.5 hours
f(4.5) = 10 × 4.5
= $45
3). For h = 10 hours
f(10) = 10 × 10
= $100
