Question

The demand equation for the Roland portable hair dryer is given by

x = 1/5(225-p^2) ( 0 ≤ p ≤ 15)

where x (measured in units of a hundred) is the quantity demanded per week and p is the unit price in dollars.

Is the demand elastic or inelastic when p = 8?
Is the demand elastic or inelastic when p = 10?
When is the demand unitary? Round the answer to two decimal places. (Hint: Solve E(t) = 1 for p).

The demand equation for the Roland portable hair dryer is given by
(225 – p?)
(0<p<15)
where x (measured in units of a hundred) is the quantity demanded per week and p is the
unit price in dollars.
a. Is the demand elastic or inelastic when p = 8?
b. Is the demand elastic or inelastic when p = 10?
c. When is the demand unitary? Round the answer to two decimal places. (Hint: Solve E(t) = 1
for p).
