If you didn't read "A vendor SOLD " well, you'll end up with an answer of $ 0 (which means the vendor supposedly sold the two coats at $ 6 0 each).
So, according to the problem, one coat is 8 0 % of the original price and the other is 1 2 0 % of its original price, and add the fact that they WILL both cost $ 6 0 . To get their original prices, we should divide.
. 8 0 $ 6 0 and 1 . 2 $ 6 0 will be equal to $ 7 5 and $ 5 0 .
Now subtract $ 1 2 0 (sum of the two prices of the coats) from the sum of the original prices.
( $ 7 5 + $ 5 0 ) − $ 1 2 0 = $ 1 2 5 − $ 1 2 0 which would be equal to 5 of loss. (Note that the dollar sign pretty much disrupts the "\boxed" format.)
