> for every two widgets i buy at regular price, i can buy a third widget for $4. i bought 9 widgets for a total of $909. find, in dollars, the regular price of a widget.
:
If you bought a total of 9, then 3 of the nine will cost only $4
Therefore you bought 6 at the regular price
:
6w = 909 - 3(4)
6w = 897
w = 897%2F6
w = $149.50 is the reg price
