Hint(s) Check My Work The Camera Shop sells two popular models of digital single lens reflex (DSLR) cameras (Camera A Price: $230, Camera B Price: $310). The sales of these products are not independent; if the price of one increases, the sales of the other will increase. In economics, these two camera models are called substitutable products. The store wishes to establish a pricing policy to maximize revenue from these products. A study of price and sales data shows the following relationships between the quantity sold (N) and price (P) of each model: NA 190 0.6 PA + 0.35 PB No = 302+0.07 PA - 0.5 PB Construct a model for the total revenue and implement it on a spreadsheet. Develop a two-way data table to estimate the optimal prices for each product in order to maximize the total revenue. Vary each price from $250 to $500 in increments of $10. Max revenue occurs at Camera A price of $ Max revenue occurs at Camera B price of $
