The original price of the school supplies was $19
Explanation:
Percentages
If the original price of the school supplies is x, and being the tax rate of 6%, then the after-tax price is x+6/100x=1.06x.
We know that final price, thus:
1.06x=20.14
x=20.14/1.06=19
The original price of the school supplies was $19
