The sales of these products are not independent of each other, but rather if the price of one increase, 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 prices (P) of each model: NA = 198 - 0.5PA + 0.25PB NB = 305 + 0.07PA - 0.6PB Construct a model for the total revenue and implement it on a spreadsheet.
