Ahmed has a computer shop and wanted to invest 1500 OMR on two types of laptops: A and B. The type A costs 245 OMR and the type B costs 290 OMR. He knows that he cannot sell more than 6 laptops. He expects that type A can be sold for 260 OMR and type B can be sold for 310 OMR. Then, the objective function to maximize the profit is O z=245x+290y O z=15x+20y O z-260x+310y O z=x+y
