=E*

d. Use the Solver Table to systematically generate the optimal solution and total profit as the unit profit of activity 1 increases in 20¢ increments from $1 to $3

(without changing the unit profit of activity 2).

Then do the same as the unit profit of activity 2 increases in 50¢ increments from $2.50 to $7.50

(without changing the unit profit of activity 1). Use these results to estimate the allowable range for the unit profit of each activity.
