Question

In a sale, the price of a microwave decreases from $50 to $39. Work out the percentage decrease in price.

a) 10%
b) 20%
c) 25%
d) 30%

Answer 1

To calculate the percentage decrease in price, subtract the new price from the original price, divide it by the original price, and then multiply by 100. In this case, the percentage decrease is 22%, which is not one of the options provided.

Step-by-step explanation:

To calculate the percentage decrease in price, you need to find the difference between the original price and the new price, divide it by the original price, and multiply by 100.

First, subtract $39 (new price) from $50 (original price) to get $11. Then, divide $11 by $50 to get 0.22. Multiply 0.22 by 100 to get 22.

Therefore, the percentage decrease in price is 22%, which is not one of the options given. The correct answer is not provided in the options provided.
