Math Problem Statement
In this problem, p is in dollars and q is the number of units.
Suppose that the demand for a product is given by (p + 8)
q + 4 = 1980. (a) Find the elasticity when p = $82. (Round your answer to two decimal places.)
(b) Tell what type of elasticity this is.
Demand is elastic.
Demand is inelastic.
Demand is unitary.
(c) How would a price increase affect revenue?
An increase in price increases revenue.
An increase in price decreases revenue.
Revenue is unaffected by price.
