Question

show 2 different approaches to calculating the sale cost of a jacket, regularly $200, which has a discount of 30%.

Answer 1

FIRST APPROACH
100-30 which is 70
You then do 70%*200 which is 140

Sorry I don't know any second approach :(

Answer 2

First approach :

`200 * 30\% \\ = 200 * (30)/(100) \\ = 60 \\ 200 - 60 = 140`

Second approach :

`200 * (100\% - 30\%) \\ = 200 * 70\% \\ = 200 * (70)/(100) \\ = 140`

Hope this helps. - M
