Mr. Cruz has 500 acres of land in which he intends to plant 2 crops corn and wheat. Itcost F 120 per acre to produce corn and P 210 per acre to produce wheat and there isP 15,000 available to this production. The yields per acre are 120 bushels of corn and210 bushels of wheat and the farmer has contracted 15,000 bushels. How much shouldthe farmer plant to maximize the profit when the net profit is P 1.30 per bushel for cornand P2 per bushel for wheat?

Mr. Raza, a drug store retailer, sells surgical face masks and KN95 masks. He can regularly acquire a supply of 200 to 400 surgical masks and 100 to 150 KN95 masks but not more than 500 items altogether. Mr. Raza can buy the surgical masks wholesale at Php10 each and sell them for Php18 each, whereas the KN95 masks cost Php25 each at wholesale but can be sold for Php 35 each. Mr. Raza wants to maximize his profit in the sales of the surgical face masks and KN95 masks. If you let x be the number of surgical masks and y the number of KN95 masks to be acquired by Mr. Raza, which among the following is a constraint in this problem? 200 ≤ y ≤400 100 < y < 150 200 ≤ x ≤ 400 x + y > 500

To accommodate more depositors, new investment products were made avanable to the small businesses and single entities. These investment products pay varying interest ranging from 3% to 10% per annum. Grabbing this opportunity to earn, a young professional has invested money in three accounts that pay 5%, 7%, and 8% in annual interest. She has three times as much invested at 8% as she does at 5%. If the total amount she had invested is PhP 80,000 and obtained interest for the year with an amount of PhP 5,750, how much money does she have in each account? Formulate the system of equations generated by this investment problem. Solve using Inverse Matrix Method.
