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

60 pounds

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.
