Pineapple Inc. is deciding how to price its two lines of laptops, one of which is a light one for travel (which is called Light) and the other is a powerful one (called Power). These products are substitutes (consumers pick between them depending on prices). Based on the data points below, estimate a linear joint demand curve - that is, a demand curve for each product that is linear in each price: Demand_Power = A_1 B_1*Price_Power C_1*Price_Light Demand_Light = A_2 B_2*Price_Power C_2*Price_Light
