$($b$)$How many hours should be assigned to each graphic designer? What is the total cost? If required, round your answer to a whole dollar amount.

$($c$)$ Suppose Lisa could be assigned more than $50$ hours. What effect would this have on the optimal solution? Explain. If an amount is zero, enter $0.$We know that the shadow price for this constraint is $,$ since the constraint is $-$ Select your answer $-$bindingnot bindingItem $29.$ Therefore, additional hours for Lisa will $-$ Select your answer $-$changenot changeItem $30$ the solution.
