Question

Michelle is out shopping and finds a bike originally valued at

$166.00. It is now on sale for 90% of the original price.

Answer 1

$149.40

Explanation:

The original value of the bike is worth 100%, and this is $166.00.

Let's work out 10%

To this, we divide the original amount by 10 (100% ÷ 10= 10%),

`166.00 / 10 = 16.60`

So now, we know that 10% = 16.60.

So, to get this to 90%, we multiply this value by 9 (10% × 9 = 90%),

`16.60 * 9 =149.4`

This means that the sale price at 90% is equal to $149.40.
