Each pound of oranges that is used for juice yields a revenue of $1.50 and incurs a variable cost (consisting of labor costs, variable overhead costs, inventory costs, and so on) of

$1.05. Each pound of oranges sold in bags yields a revenue of $1.50 and incurs a variable cost of $0.70.

a. Determine how Sunblessed can maximize its profit.

b. Use SolverTable to determine how a change in the cost per bag of oranges changes the optimal solution.

c. Use SolverTable to determine how a change in the amount of grade 9 oranges available affects the optimal solution.

d. Use SolverTable to determine how a change in the required average quality required for juice changes the optimal solution.
