You see a sneaker resell opportunity: you can buy a limited pair for R2,000 now and expect to sell it in 3 years for R3,200. If a simple interest savings account offers 10% per year, which option gives you more money after 3 years?

You take a hire-purchase loan of R15,000 for a laptop at 18% simple interest per year, repayable over 2 years with a 10% deposit. What is the total amount you will actually pay for the laptop?

Inflation is currently 6% per year. If a loaf of bread costs R15 today, what will it cost in 5 years if inflation stays constant? (Use the compound interest formula.)
