20% of the regular price was off.
So 80% of the regular price stayed on.
$33.96 was that 80% of the regular price.
(0.8) · (regular price) = $33.96
Divide both sides by (0.8).
Regular price = ($33.96) / (0.8)
<em>Regular price = $42.45</em>

Since a Nickel is worth 5 cents ($0.05)
And a Quarter is worth 25 ($0.25)
and theres 22 coins
8 of those coins would be nickels which would mean we add 8 nickels up
