I can buy 9 footballs for R150 each, but get a 20% discount if I buy ten. How much can I save if I buy 10 footballs instead of 9. On the answers below
R150
R20
R170
R100
To calculate the savings, you need to find the difference between the regular price of 10 footballs and the discounted price.
Regular price of 10 footballs = 10 * R150 = R1500
20% discount on 10 footballs = 0.20 * R1500 = R300
Therefore, you can save R300 if you buy 10 footballs instead of 9.
The correct answer is R300.
