A salesperson sold 24 laptops at a 6% discount. Calculate her commission based on the tiered structure: 0% up to 500,000, 3% for 500,001-750,000, 5% for 750,001-1,000,000, and 8% above 1,000,000.

Original price per laptop = Ksh. 42,000.
Discount = 6%.
Discount amount per laptop = $0.06 \times 42,000 = 2,520$ Ksh.
Selling price per laptop = $42,000 - 2,520 = 39,480$ Ksh.

Total sales = $39,480 \times 24 = 947,520$ Ksh.

• For sales up to Ksh. 500,000: 0% commission.
• For the first Ksh. 250,000 above Ksh. 500,000 (i.e., from Ksh. 500,001 to Ksh. 750,000): 3% commission.

• For any amount above Ksh. 1,000,000: 8% commission.
