The calculated cost to park at the airport for 6 hours is $36
How much would it cost to park at the airport for 6 hours.
From the question, we have the following parameters that can be used in our computation:
t P(t)
1 16
2 20
3 24
4 28
A linear function is represented as
P(t) = mt + c
Using the points (1, 16) and (2, 20), we have
m + c = 16
2m + c = 20
Subtract the equations to calculate m
So, we have
2m - m + c - c = 20 - 16
m = 4
Recall that
m + c = 16
So, we have
4 + c = 16
c = 12
This means that the function is
P(t) = 4t + 12
The cost to park at the airport for 6 hours is calculated as
P(6) = 4 * 6 + 12
P(6) = 36
Hence, the cost to park at the airport for 6 hours is $36
