A person wants to order ferns for his garden. He checked the price at a nursery and found that the nursery charges $9 for delivery and $5 for each plant ordered. He also
noted that there are no delivery charges for an order of $70 or more. Based on his
findings, he wrote the following functions:
. f(n) = 9+5n to represent the cost of n plants when a delivery charge is included
• g(n) = 5n to represent the cost of n plants with no delivery charge
Match the domain to the function.
All positive integers All positive integers less than 14
All integers greater than or æqual to 70
All positive integers less than 70
All non-negative integers less than 14
All non-negative integers less than 70
All integers greater than or equal to 14

1. 45/6 = 7.5
7.5*10 = 75
So the penguin walks 75 ft in 45 seconds.

2. 45/10 = 4.5
4.5*6 = 27
The penguin takes 27 seconds to walk 45 ft.
