A kennel charges $20 a day to board dogs, where d represents the number of days. Upon arrival, each dog must have a bath that cost $15, where cost is represented by C(d). Write a function rule to represent this situation. C(d) = 20d + 15 C(d) = 15d + 20 C(d) = 20d - 15 C(d) = 15d - 20

C = 20d + 15.

$20/day means

cost = 20d

add to that the $15 bath
so, what do you think?

The correct function rule to represent this situation is C(d) = 20d + 15.

To explain how to arrive at this answer, first let's break down the information given. The kennel charges $20 per day to board dogs, and since d represents the number of days, it makes sense to multiply the number of days by the daily rate of $20. This gives us 20d.

Additionally, upon arrival, each dog must have a bath that costs $15. So regardless of the number of days, there is an initial cost of $15 for the bath.

To calculate the total cost (C(d)), we need to sum up the cost of boarding the dog for d days and the cost of the bath. Therefore, the function rule representing this situation is C(d) = 20d + 15.
