Consider the following function.

f(t) = t8

(a)Find the relative rate of change.

 

(b)Evaluate the relative rate of change at t = 1.Evaluate the relative rate of change at t = 8.

 

The demand function for beer is given below, where p is the retail price and

D(p)

is the demand in gallons per capita. For the demand function, find the elasticity of demand E(p) for any price p. [Note: You will find that demand is inelastic. This means that taxation, which acts like a price increase, is an ineffective way of discouraging liquor consumption, but is an effective way of raising revenue.]

D(p) = 5.945p−0.141

E(p) =
