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.
R150
R20
R170
R100
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.
