Question
2) Pedro needs to call his classmates to give them final instructions about their class project. He thinks he will need about 2 minutes to talk to each one of them. If his phone has a current load worth P425 and a call would cost him P6.15 per minute, how many of his classmates will he be able to talk to? 3) Maria was asked to go to the market to buy 2 kilos of pork, kilo of garlic, and 6 pieces of saba. One kilo of pork costs P 215, 1 kilo of garlic costs P 105, and one piece of saba costs P2.30. If Maria is given P 700, will she be able to buy everything she was asked to buy? If yes, how much change is left, if any? 4) Miguel agrees to lend you money for a monthly interest of 12%. How much will you pay him next month if you borrowed P 500? 5) In a school, there are 450 students in total. If 2/3 of the total population is boys, find the number of girls in the school and their percentage.
