A mutual fund manager must decide how much money to invest in Atlantic Oil (A) and how much to invest in Pacific Oil (P). At least 60% of the money invested in the two oil companies must be in Pacific Oil. A correct modeling of this constraint is

Step-by-step explanation:

Amount of money to invest in Atlantic Oil= A

Amount of money to invest in Pacific Oil = P

Total money invested in the two oil companies = A+P

Since at least 60% of the money invested in the two oil companies must be in Pacific Oil

Hence the required model is
