a knife was originally sold RM15.the price was marked down by 19% and finally marked down an additional 5%.What is the final reduced price.?

Answer 1

P1 = 100%-19% = 81% of original price.
P1 = 0.81 * 15 = $12.15. = Sale price.

P2 = 100%-5% = 95% of P1.
P2 = .95 * P1 = .95 * 12.15 = $11.54 =
Final sale price.

Answer 3

Po = $7,000 = Original price.

P1 = 100% - 8% = 92% of Po
P1 = 0.92 * 7000 = $6,440 = Resale price

P2 = 100% + 18% = 118% 0f P1.
P2 = 1.18 * 6440 = $7599.20=List price.
