Eric bought a picnic table on sale for 50% off the original price. The store charged 10% tax and his final cost was $22.00. What was the original price of the picnic table?
----------------------
Since tax was the last thing added to get the cost of $22 take
90% of 22 to get the final selling price:
0.90*22 = $19.80
------------------
So, 19.80 is half the original price.
Therefore:
original price = 2(19.80) = $39.60
