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.

Question

R150
R20
R170
R100

Answer 1

To find out how much you can save if you buy 10 footballs instead of 9, first calculate the total cost of buying 9 footballs: 9 footballs * R150/football = R<<9*150=1350>>1350
Next, calculate the discount amount: R1350 * 20% = R<<1350*20*.01=270>>270
Finally, subtract the discount amount from the total cost of buying 9 footballs to find the savings: R1350 - R270 = R<<1350-270=1080>>1080

Therefore, you can save R1080 if you buy 10 footballs instead of 9.
