Answer:
C(r) = 100 + 55r
C(6) = $430
Step-by-step explanation:
Fixed charges = $100
Charges per room = $55
A. function that represents the total amount he charges for designing a certain number of rooms.
Let
r = number of rooms
C = Total amount charged
C(r) = 100 + 55r
The function is C(r) = 100 + 55r
B. What is the value of the function for an input of 6, and what does it represent
C(r) = 100 + 55r
When r = 6
C(6) = 100 + 55 * 6
= 100 + 330
= 430
C(6) = $430
This means that the amount charged for 6 rooms is $430
