4. The output below is from a linear programming model where the intention was to maximize profit. X1 represented the number of adult ticket sales and X2 represented the number of child ticket sales. Answer the questions below.

State the objective functionB. What is the maximum prot? C. How rnanj.r adult tickets should be sold to maximize prot? D. How rnanj.r child tickets should be sold to maximize prot? E. What are the total unused resources for constraint 4'? e? E" F. If the prot per child ticket was to increase to $65, would the optimal solution G. If the second constraint could experience an increase om 60 to 61, what would be the change in the value of the prot
