Polly woodsides is planning to invest her savings of $100,000 into three stocks: ABC, PQR, and XYZ. For each dollar invested, she can expect to get 4%, 6.5%, and 7.5%, respectively. Her investment policy is that:

a.)She would invest at most 40% of her money in any one stock.

b) The amount of money invested in ABC should be at least as much as the amount invested in XYZ.

c) At least 25% of her money should be invested in PQR.

Formulate an Linear Program to maximize the total return on Polly's investment
