Now suppose that every customer that buys a suit is willing to pay up to $50 for a fancy shirt. If the customer does not buy a suit, their value of a fancy shirt is $0 (i.e., they don't buy a shirt alone). The marginal cost (wholesale price) of a shirt is $20. If the store sells suits and shirts, what are the optimal prices? profits? (i.e. come up with two price points - an optimal price for suits and an optimal price for shirts, along with the total profits)
