The price of a pair of trousers was decreased by 22% to $30. What was the original price of the trousers?

Answers

Answer:

$38.46

Step-by-step explanation:

It is given that the price of a pair of trousers was decreased by 22% to $30.

Let $x be the original price of the trousers.

22% less of original price is equal to $30.

$x-(22)/(100)x=30$

$x-0.22x=30$

$0.78x=30$

Divide both sides by 0.78.

$x=(30)/(0.78)$

$x\approx 38.46$

Therefore, the original price of the trousers is $38.46.
