Walks Softly, Inc. sells customized shoes. Currently, they sell 10,000 pairs of shoes annually at an average price of $60 a pair. They are considering adding a lower-priced line of shoes which sell for $49 a pair. Walks Softly estimates they can sell 5,000 pairs of the lower-priced shoes but will sell 1,000 less pairs of the higher-priced shoes by doing so. What is the amount of the sales that should be used when evaluating the addition of the lower-priced shoes? Atsakymas
