Many times, the selling price of a product, p, is related to the demand, D, according to the relationship p=a-bD. However, a company has found that the price of their product can be related to demand ( in units per year) according to the following equation: p= $88.5 – (0.5)D0.5 . In addition, there is a fixed cost of $20,000 per year and the variable cost to manufacture the product is $20 per unit. a. What level of demand maximizes total revenue and the maximum revenue? b. What level of demand maximizes total profit for this product and the maximum profit?
A construction crew (that is currently unemployed and receiving $10/hr. in benefits) to fix a road. The cement is purchased from a rip-off monopolist that charges $10/bag more than anyone else. The Follow-up maintenance will be done after 1 year, using a different crew that we will assume is not unemployed. We will also assume the interest rate is 7%. The cost estimate provided by the contractor’s accountant is given in the table below:

Derek and Maria are now trying to predict how much money they will raise for their club from the car
wash. They determine their costs to be about $0.50 in materials to wash each car as well as their initial
start-up costs of $220. They model their costs using the function c(x) = 0.5x + 220. They will charge
$10 for each car wash. Additionally they received a $50 donation from one of the member's parents.
They model their revenue using the function r(x) = 10x + 50.
The profit from the car wash, p(x), can be determined by finding r(x) − c(x).
Part A: Find the function that represents the profit from the car wash.
Part B: What is the meaning of the y-intercept of p(x) in terms of the situation?
