풀이 예제
An 80 jacket with 25% off and 8% tax
You save 25% of 80 = 20.00, so the sale price is 60.00.
Tax is 8% of 60 = 4.80.
The final price is 60.00 + 4.80 = 64.80.
자주 묻는 질문
Is 25% off and then 8% tax the same as 17% off?
No. The tax is worked out on the lower sale price, so the final price is 80 × 0.75 × 1.08 = 64.80, not 80 × 0.83 = 66.40.
Does the order of discount and tax matter?
For the final price, no — multiplying by 0.75 and 1.08 gives the same result either way. Only the tax amount shown differs.
