Sale Price is $160
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!

(A) $96
(B) $120
(C) $128

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
