Question

.A dress has a thirty percent discount applied and is on sale for 63 pound. What was the original price of the dress before the reduction?

Answer 1

Answer:

The original price of the dress before the reduction was 90 pound.

Step-by-step explanation:

This question can be solved using a rule of three. The current price, which is 63 pound, is 100 - 30 = 70% = 0.7.

The original price is x pound, and is 100% = 1. So

x pound - 1

63 pound - 0.7

$0.7x = 63$

$x = \frac{63}{0.7}$

$x = 90$

The original price of the dress before the reduction was 90 pound.
