Let $x be the cost price of this pair of shoes.
x(1+20%)=900
1.2x=900
x=750
So, the cost price of this pair of shoes is $750

The cost price is:

$900 / (1+20%)
=$750

Hoped this helps!^^
參考: Cost price X (1+profit percent) = selling price
2007-01-13 6:14 am
900x(1-20%)
=$720
2007-01-13 6:13 am
900-900x0.2
=$720
2007-01-13 6:12 am
900*(1+20%)
=$1080
