Adım Adım Çözüm

1
Calculate the discount amount.
20% of 300.00=0.20×300.00 = 0.20 × 300.00 = $60.00
The discount must be determined to find the sale price.
2
Subtract the discount from the original price.
300.00−300.00 - 60.00 = $240.00
This provides the discounted sale price upon which tax is calculated.
3
Calculate the sales tax on the sale price.
5% of 240.00=0.05×240.00 = 0.05 × 240.00 = $12.00
Sales tax is always applied to the final discounted price of the item.
4
Add the sales tax to the sale price.
240.00+240.00 + 12.00 = $252.00
This determines the final total cost the customer must pay.

You can solve this using multipliers in a single step: Total Cost = Original Price × (1 - Discount Rate) × (1 + Tax Rate). Here, 300.00×0.80×1.05=300.00 × 0.80 × 1.05 = 252.00.
