please answer the correct answer with steps. Thank you so much

A supplier produces a product at the cost of $0.5 per unit (i.e., c=0.5) and sells it to a retailer at the wholesale price w. The retailer, in turn, sells the product to customers at a retailer price p. The two firms are considering a revenue sharing contract as follows. The supplier sells the product free of charge (i.e., w=0) to the retailer, but for each product sold the supplier gets 0.7p and the retailer gets 0.3p. The demand for the product is not random, but is sensitive to price, given as D(p)=100-50p. Assume that inventory-related costs are zero. What is the retail price p that maximizes the retailer's own profit? O 0.7 0.5 O 1.5 0 1 O 0.3
