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
[tex]0.7x = 63[/tex]
[tex]x = \frac{63}{0.7}[/tex]
[tex]x = 90[/tex]
The original price of the dress before the reduction was 90 pound.
