One strategy after determining the sale price could be use answer choices and add 25% to each answer choice. The answer which get you to $160 after adding 25% is the correct answer choice. In this case its$128 + 25% of $128 =$160!

How much did the retailer originally pay for the dishwasher?

(A) $96 (B)$120
(C) $128 (D)$144
(E) $160 Short (.8*$200)=1.25C
$160=1.25C C = $$\frac{160}{1.25}=128$$ Explanation The trick here is to avoid getting bamboozled by language. 1) Retail price = $$200$$, which is discounted by 20% to equal 2) Actual sell price, SP SP is 20% off of$200
SP = 80% of $200 SP = (.80 *$200) = $160 3) Profit and cost? Profit is 25% of the original cost, C, so Profit = .25C (Sell price - profit) = Cost $$160 - .25C = C$$ $$160 = 1.25C$$ $$C=\frac{160}{1.25}=\frac{160}{(\frac{5}{4})}=(160*\frac{4}{5})=128$$ The retailer originally paid$128 for the dishwasher
