b.
To graph: The system of inequalities.
Given: A man has at most 80 brownies and cookies. The cost of each brownie $0.10 and cost of each cookie $0.05.
Explanation:
The system of inequalities,
The graph of the inequalities,
Now choose any one point of the feasible region. That point satisfy the both situation of the problem.
c.
To find: Each desert which maximize the profit.
40 and 40
Given: A man has at most 80 brownies and cookies. The cost of each brownie $0.10 and cost of each cookie $0.05. A profit of $0.25 on each brownie and $0.20 on each cookie.
Explanation:
The optimization function,
From the graph the corner points and find the profit.
The profit is maximum when 40 units of brownies and 40 units of cookies sale.
