Step 7: Teach the solution to a peer. If you can explain the manual’s logic aloud, you truly know it.

Problem 2: Present Worth (Discounting)

Problem: A certain machine will be worth P100,000 after 10 years. If money is worth 6% compounded annually, how much should you invest now to have that amount in the future?

Solution:

• Given: $F = 100,000$, $i = 0.06$, $n = 10$, Find $P$.
• Formula: $P = F(1 + i)^-n$
• Calculation: $$P = 100,000 (1 + 0.06)^-10$$ $$P = 100,000 (0.55839)$$ $$P = 55,839.48$$
• Answer: P55,839.48

Problem 1: Single Payment (Compound Interest)

Problem: Mr. Cruz deposited P50,000 in a bank that pays 8% interest compounded annually. How much will he have in his account after 5 years?

Solution:

• Given: $P = 50,000$, $i = 0.08$, $n = 5$, Find $F$.
• Formula: $F = P(1 + i)^n$
• Calculation: $$F = 50,000 (1 + 0.08)^5$$ $$F = 50,000 (1.4693)$$ $$F = 73,466.40$$
• Answer: P73,466.40
