# 7-4 written assignment instruction: excel solver practice

The MacDonald sells two popular packages of breakfast all-day-long: Mac A and Mac B . The sales of these products are not independent of each other (in economics, we call these substitutable products, because if the price of one increases, sales of the other will increase).

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 ( Q ) and prices ( P ) of each model:

QA = 20 – 0.62PA + 0.30PB

QB = 29 + 0.10PA – 0.60PB

a. Construct a model for the total revenue and implement it on a spreadsheet.

b. Develop a two-way data table to estimate the optimal prices for each product in order to maximize the total revenue.

c. Use “Solver” to find the optimal prices.
