Answer: Colton will earn $117 if he worked for 15 hours and made 8 deliveries.
Step-by-step explanation:
Colton earns 7 per hour plus 1.50 for each pizza delivery. This is represented by the expression,
7h+1.50d
Which can be used to find the total earnings for h hours and after d deliveries have been made.
If Colton worked for 15 hours and made 8 deliveries, then the total amount of money that Colton would earn is
7 × 15 + 1.50 × 8
= 105 + 12 = $117
