  1. Mpho earns R18 400 per month. He receives a bonus equal to 150% of one month's salary. What is his total income for that month?

    Answer: R46 000

    Bonus = 150% × R18 400 = R27 600; total = R18 400 + R27 600 = R46 000.

  2. A cell phone contract: pay R299 per month for 24 months with R0 upfront. The phone's cash price is R5 400. How much more do you pay on the contract?

    Answer: R1 776

    Contract total = R299 × 24 = R7 176; extra = R7 176 − R5 400 = R1 776.

  3. A pie chart shows a household budget. Savings is 12% of income. If savings = R2 160, what is the monthly income?

    Answer: R18 000

    Income = R2 160 ÷ 0.12 = R18 000.

  4. A retailer buys shirts at R240 each and sells them at R318. A sale offers 15% off. Is there still a profit?

    Answer: Yes, R30.30 profit

    15% off R318 = R270.30; profit = R270.30 − R240 = R30.30.

  5. A graph shows population growth from 12 000 (2010) to 15 600 (2020). What is the percentage growth over the decade?

    Answer: 30%

    Growth = 3 600; % = (3 600 ÷ 12 000) × 100 = 30%.

  6. Simple interest on R7 500 at r% per annum for 2 years amounts to R1 500. What is r?

    Answer: 10%

    r = I ÷ (P × t) = 1 500 ÷ (7 500 × 2) = 1 500 ÷ 15 000 = 0.10 = 10%.

  7. After a 25% increase, a product costs R625. What was the original price?

    Answer: R500

    R625 = 125% of original; original = R625 ÷ 1.25 = R500.
