certain cleaning company cleans professional offices and believes its staff can clean up to 300 office units a week at a labor and supply cost of $58 per unit. Preliminary pricing surveys indicate that if that if the company charges $100 per unit, it will have clients for 300 units. For every $5 price increase it can expect a demand of 10 fewer units.   Assume the demand, s, is a linear function of price p. Find an equation for demand as a function of price.   Find the Revenue and Cost functions, both of which are dependent on price p.   Write the Profit function.
