Please show steps in excel, I am confused about what information to put in the solver (thanks!)

John Sweeney is an investment advisor who is attempting to construct an "optimal portfolio" for a client who has $400,000 cash to invest. There are ten different investments, falling into four broad categories that John and his client have identified as potential candidates for this portfolio.

The following table lists the investments and their important characteristics. Note that Unidyde Equities (stocks) and Unidyde Debt (bonds) are two separate investments, whereas First General REIT is a single investment that is considered both an equities and a real estate investment.

Category	Investment	Exp. Annual After Tax Return	Liquidity Factor	Risk Factor
Equities	Unidyne Corp.	15.0%	100	60
	Col. Mustard Restaurant	17.0%	100	70
	First General REIT	17.5%	100	75
Debt	Metropolitan Electric	11.8%	95	20
	Unidyne Corp.	12.2%	92	30
	Lemonville Transit	12.0%	79	22
Real Estate	Fairview Apartment Partnership	22.0%	0	50
	First General REIT	(see above)	(see above)	(see above)
Money	T-Bill Account	9.6%	80	0
	Money Market Fund	10.5%	100	10
	All Saver's Certificate	12.6%	0	0

Formulate and solve a linear program to accomplish John's objective as an investment advisor which is to construct a portfolio that maximizes his client's total expected after-tax return over the next year, subject to a number of constraints placed upon him by the client for the portfolio:

1.	Its (weighted) average liquidity factor must be at least 65.
2.	The (weighted) average risk factor must be no greater than 55.
3.	At most, $60,000 is to be invested in Unidyde stocks or bonds.
4.	No more than 40% of the investment can be in any one category except the money category.
5.	No more than 20% of the investment can be in any one investment except the money market fund.
6.	At least $1,000 must be invested in the money market fund.
7.	The maximum investment in All Saver's Certificates is $15,000.
8.	The minimum investment desired for debt is $90,000.

9. At least $10,000 must be placed in a T-Bill account.

THE DECISION VARIABLES TO BE USED ARE.

X_j = $ invested in investment j;

where j =

2(Col. Must.),

3(1st Gen REIT),

4(Met. Elec.),

5(Uni Debt),
