Deirdre works for a moving company. Her job includes giving clients a price for their move. Deirdre has one function, h(r) = 4r, which gives the number of hours h to pack up a number of rooms r. She has a second function, c(h) = 40h, that gives the price c for the number of hours of packing h. What is the function that gives the price c for a number of rooms r?

The function that gives the price for a number of rooms is .

Step-by-step explanation:

This problem shows a case of composition between two function, which is defined as follows:

(Eq. 1)

Where:

 - Price, measured in US dollars.

- Packing time, measured in hours.

- Number of rooms, dimensionless.

If we know that and , then the composite function is:

(Eq. 2)

The function that gives the price for a number of rooms is .
