#### Solution Preview

A. Given that there was a rebate of $1 off the regular price of $50, we can use the elasticity of demand formula to find the price elasticity of demand.

Price Elasticity of Demand = (% Change in Quantity)/(% Change in Price)

There are two ways to calculate this, the first is:

Price Elasticity of Demand = ...

#### Solution Summary

The optimum price is determined for an imperfect competitive market.
