What will my percentage saving be if i buy something in a sale that offers 3 for the price of 2?
:
An easy understandable way is choose an original price for one item, say $6
then two cost $12
then three cost 12%2F3 = $4
:
That is cost per item reduction of $2
:
The per cent saving: 2%2F6 * 100 = 331%2F3 %
