Jason Wright is a part-time MBA student who would like to optimize his financial decisions. Currently, he has $16,000 in his savings account. Based on an analysis of his take-home pay, expected bonuses, and anticipated tax refund, he has estimated his income for each month over the next year. In addition, he has estimated his monthly expenses, which vary because of scheduled payments for insurance, utilities, tuition and books, and so on. The table below summarizes his estimates:

Month	Income	Expenses
Jan	$3,400	$ 3,360
Feb	$3,400	$ 2,900
Mar	$3,400	$ 6,600
Apr	$9,500	$ 2,750
May	$3,400	$ 2,800
Jun	$5,000	$ 6,800
Jul	$4,600	$ 3,200
Aug	$3,400	$ 3,600
Sep	$3,400	$ 6,550
Oct	$3,400	$ 2,800
Nov	$3,400	$ 2,900
Dec	$5,000	$ 6,650

Jason has identified several short-term investment opportunities:

• A 3-month CD yielding 0.60% at maturity

• A 6-month CD yielding 1.42% at maturity

• An 11-month CD yielding 3.08% at maturity

• His savings account yields 0.0375% per month

To ensure enough cash for emergencies, he would like to maintain at least $2,000 in the savings account. Jason’s objective is to maximize his cash balance at the end of the year. Develop a linear optimization model to find the best investment strategy.
