A factory owner who employes m workers finds that they produce
q=2.2 m(2.2 m+16)^(3/2) units of product per day.

The total revenue R in dollars is


The marginal-revenue product is defined as the rate of change of revenue with respect to the number of employees. Therefore

Marginal revenue product=dR/dm

If q and R are given as above then, when m= 15, the marginal-revenue product is ________dollars/(one worker).

This means that if employee number 16 is hired, revenue will increase by approximately_____dollars per day
