Fund A sells for $$$$15$ a share and has a$3-$year average annual return of $$$$0\mathrm{.}28$ a share. The beta value is $1\mathrm{.}07.$ Fund B sells for $$$$17$ a share and has a$3-$year average annual return of $$$$0\mathrm{.}97$ a share. The beta value is $0\mathrm{.}77.$ Jonquin wants to spend no more than $$$$2500$ investing in these two$$ funds, but he wants to obtain at least $$$$90$ in annual revenue. Jonquin also wants to minimize the risk. Determine the number of shares of each fund that Jonquin should buy. Set up the linear programming problem. Let a represent the number of shares in Fund$$ A$,$ b represent the number of shares in Fund$$ B$,$ and z represent the total beta value.
