-The profit function for sales of two models of television sets at a chain discount store is given by where x is the number of sales per week of model A, and y is the number of sales per week of model B. Find Px(10, 15) and interpret the result.
A) At a sales level of 10 units of model A and 15 units of model B, increasing sales of model A by one unit and holding
Sales of model B at 15 units will increase profit by approximately $60
B) At a sales level of 10 units of model A and 15 units of model B, increasing sales of model A by one unit and holding
Sales of model B at 15 units will increase profit by approximately $80.
C) At a sales level of 10 units of model A and 15 units of model B, increasing sales of model A by one unit and holding
Sales of model B at 15 units will increase profit by approximately $120
