Question 

(a) Ed invests $500 in an account paying r% per year simple interest.
At the end of 14 years the total amount in Ed’s account is $675.

Find the value of r.

(b) Eva invests $400 at a rate of 2.2% per year compound interest.

Calculate the total interest earned at the end of 11 years.

(c) Erin invests $700 at a rate of p% per month compound interest.
At the end of 21 years the value of Erin’s investment is $1074, correct to the nearest dollar.

Calculate the value of p.

▶️ Answer/Explanation
Solution

(a) r = 2.5

Simple interest formula: I = P × r × t. Total amount = $675 – $500 = $175 interest. Solving 500 × r × 14 = 175 gives r = 2.5%.

(b) $108.18

Compound interest formula: A = P(1 + r)^t. Calculation: 400 × (1.022)^11 ≈ 508.18. Subtract principal: 508.18 – 400 = $108.18 interest.

(c) p = 0.17

Monthly compounding over 21 years (252 months). Using A = P(1 + r)^n: 1074 = 700(1 + p/100)^252. Solving gives p ≈ 0.17% per month.
