Question

The store has a discount on shoes that were originally 50 but was brought down by 20%. What is the new price?​

Answer 1

The new price will be 40.

Explanation:

The question states that the price was reduced by 20%. The implication is that the 20% price cut is relative to the original price, which is 50.

What will be 20% of 50?

Twenty percent is the same (in value) as twenty divided by a hundred. That is:

`\displaystyle 20\% = (20)/(100)`.

To find 20% of 50, multiply 50 with 20%, which is the same as multiplying with
`\displaystyle (20)/(100)`.

`\displaystyle 50 * 20\% = 50 *(20)/(100) = (50* 20)/(100) = (1000)/(100) = 10`.

In other words, when the original price was brought down by 20%, the price was cut by 10. As a result, the new price will be
`(50 - 10) = 40`.
