There is a chair factory. The number of chairs completed can be determined by the equation C = 41, where C is the number of chairs and 1 is the number of workers that are making chairs, identify the unit rate.

The given equation is C=41, where C is the number of chairs, and 1 is the number of workers that are making chairs.

For simplicity, denote the number of workers by n.

So, replace 1 by n in the equation, we have

C=4n

Note that C/n is the number of chairs made by one worker, which is the unit rate.

Hence the required unit rate is 4.
