a$)[4$ points$]$ Are there multiple optimal solutions to this problem? Why or why not?

b$)[5$ points$]$ Suppose the profit per gallon of banana changes to $$1\mathrm{.}00.$ Will the optimal solution

change, and what can be said about the effect on total profit $($increase or decrease$)?$

c$)[5$ points$]$ Making no other changes, what would the profit of chocolate ice cream need to

change for it to possibly be optimal for the Ken and Larry, Inc to start making chocolate ice

cream? Why?

d$)[6$ points$]$ If the vanilla ice cream profit increases from $$0\mathrm{.}9$ to $$0\mathrm{.}92$ and the profit of the banana

ice cream decreases from $$0\mathrm{.}95$ to $$0\mathrm{.}93.$

i$.$ Will the optimal solution $(($i$.$e$.,$ optimal value of decision variables$)$ change? Why?

ii$.$ What will the optimal total profit change to$?($Write "resolve" if changes to the optimal total

profit cannot be determined without resolving the LP$.)$ Show your work to support your answer

Please advice how I got part C wrong, I$\text{'}$m not sure what I did.
