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.?

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.

A hi-fi set was purchased for RM7000.The hi-fi set will be resold by offering an 8% discount.If the retailer wants a 18% gross profit based on the net retail price,find the list price.

pls help me ?

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.

To find the final reduced price, we need to calculate the first discount and then apply the second discount to the discounted price.

STEP 1: Calculate the first discount
The first discount is 19% off the original price of RM15. To find the value of the discount, we multiply the original price by the discount percentage:
Discount = Original Price * (Discount Percentage / 100)
Discount = RM15 * (19 / 100)
Discount = RM2.85

The discounted price after the first discount is calculated by subtracting the discount from the original price:
Discounted Price = Original Price - Discount
Discounted Price = RM15 - RM2.85
Discounted Price = RM12.15

STEP 2: Calculate the second discount
The second discount is an additional 5% off the discounted price of RM12.15. Again, we calculate the value of the discount:
Discount = Discounted Price * (Discount Percentage / 100)
Discount = RM12.15 * (5 / 100)
Discount = RM0.6075 (rounded to 2 decimal places)

The final reduced price, after applying both discounts, is calculated by subtracting the second discount from the discounted price:
Final Reduced Price = Discounted Price - Discount
Final Reduced Price = RM12.15 - RM0.6075
Final Reduced Price = RM11.5425 (rounded to 2 decimal places)

Therefore, the final reduced price of the knife is RM11.54.
