A) 12

D) 88
E) 100

vitorcbarbieri - The question is a little confusing. There are two sell prices: one before the discount ("marked price") the other, after the discount.

The "marked price" gives you the cost of the item. Discounted price gives you the profit. And you derive the marked price from the discount price.

Actual discounted price yields original price

Marked price before successive discounts of 20 and 30 percent?

(I think the following formula is what you're after. Not positive.)*

(a + b + $$\frac{ab}{100})$$ percent

$$(20 + 30 + \frac{600}{100})$$ percent

$$(20 + 30 + 6) = 56$$ percent

The discounted price is 56% of original marked price, call it x

$112 = .56x $$\frac{112}{(\frac{56}{100})}= 112 *\frac{100}{56}=200$$ = original price Cost price? The marked price is 100% higher than the cost price, c.$200 = c + $$\frac{100}{100}$$c = 2c
$200 = 2c c =$100

Profit?
Sell Price - Cost Price
$112 - 100 =$12

Hope it helps.

*You can also derive this discount percentage by taking: 1) first discount: 1 - .20 = .80; 2) second discount: 1 - .30 = .70. Multiply them: (.8 * .7) = .56
