Question

In a sale there is 25% off all prices. A chair costs £45 in the sale. How much was it before the sale?

Answer 1

Answer:

60 pounds

Step-by-step explanation:

Let the normal price be p.  The "25%-off" sale price is then 0.75p, and this 0.75p equals 45 pounds.  Dividing both sides by 0.75 results in p = 60 pounds.
