A watch store owner decided to offer 20% discount for a particular brand of watch that sells at P35,000.00. By doing so, his average sales increased from 5 watches to 12 watches a day. If he bought one watch at a price of P22,000.00 from the supplier, by how much was his daily profit increased or decreased by offering such discount on the watch? Michelle went to Baguio and bought 20 jars of strawberry jam for P3,500.00 with 1 5% discount. When she got back to Manila, she sold 10 of the jars for a total of P1,800.00 and the rest as P185.00 each. How much profit did Michelle again?
