If you buy 10 footballs at a discounted price, you will pay 20% less for each football.
The original price of each football is R150.
20% of R150 is (20/100) * 150 = R30.
So, each football will be discounted by R30.
Therefore, the discounted price of each football will be R150 - R30 = R120.
If you buy 9 footballs, you will pay 9 * R150 = R1350.
If you buy 10 footballs, you will pay 10 * R120 = R1200.
Therefore, you can save R1350 - R1200 = R150 if you buy 10 footballs instead of 9.
The original price of each football is R150.
20% of R150 is (20/100) * 150 = R30.

If you buy 9 footballs, you will pay 9 * R150 = R1350.
If you buy 10 footballs, you will pay 10 * R120 = R1200.
Therefore, you can save R1350 - R1200 = R150 if you buy 10 footballs instead of 9.
