Answer:
Constant of proportionality = 2.25
What this value means is that the ratio between the daily fee for docking a boat at a marina in port and the length of the boat is 2.25
Step-by-step explanation:
We are told that the daily fee for docking a boat at a marina in port Canaveral is proportional to the length of the boat.
Let D be represent the daily fee and let the lent be L.
D ∝ L
Let the constant of proportionality be k.
Thus;
D = kL
k = D/L
For length of 15 ft;
k = 33.75/15
k = 2.25
For length of 17 ft
k = 38.25/17
k = 2.25
For length of 20 ft
k = 45/20
k = 2.25
Foe length of 21 ft
k = 47.25/21
k = 2.25
This means the formula for the relationship between the daily fee and boat length is; D = 2.25L
Thus, D/L = 2.25
What this means is that the ratio between the daily fee for docking a boat at a marina in port and the length of the boat is 2.25
