The number of devices a particular manufacturing company can produce is a function of the number of hours spent making the devices.

On average, 4 devices are produced each hour. Assume that devices are produced at a constant rate.

What is the constant rate, C, of producing the devices?

• $C\ =\ \frac{4}{1}$
  

• $C\ =\ \frac{1}{4}$

• $C\ =\ 1$
