1) Suppose you invest PhP100,000 in a project that guarantees 15% interest annually, provided your money is tied up for 5 years (i.e. you cannot withdraw any amount within the five-year period). Show the difference in the annual gross returns between a simple interest and a compounded interest.

2) The basic charge and environmental charge reflected in a Manila Water bill is PhP309.97 and PhP62.07, respectively. What percent of the basic charge is the environmental charge? In the same bill, the total Vatable current charge is P373.93. How much is the 12% VAT?

3) Senior citizens and persons with disability are given a 20% discount on food items. If a child with disability gives a one hundred peso bill to pay for ice cream that costs PhP55 (inclusive of VAT), how much change will the child receive?

4) Mrs. Reyes treated her daughter and her 3 classmates to merienda at a burger restaurant. Based on the listed prices (inclusive of VAT) in the menu, their orders would amount to a total of PhP1,000. If there is a 5% service charge based on the total amount, and, Mrs. Reyes avails of her senior citizen discount, how much will Mrs. Reyes pay?

5.)  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 PhP215, 1 kilo of garlic costs PhP105, and one piece of Saba costs PhP2.30 If Maria is given PhP700, will she be able to buy everything she was asked to buy? If yes, how much change is left, if any?

6.)  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 cellular phone has a current load worth PhP425 and a call would cost him PhP6.15 per minute, how many of his classmates will he be able to talk to?

7.)  Miguel agrees to lend you money for a monthly interest of 12%. How much will you pay him next month if you borrowed PhP500?

8.)  A house and lot in a certain subdivision is being sold for PhP1,013,450. If the lot measures 210 square meters, what is its cost per square meter?
