3. Find the total cost of each item, using 12% HST.
   

   	Item	Cost	HST (12%)	Total Cost
   A	T-shirt	$14.99	$\begin{equation}\begin{split} \dfrac{\text{X}}{14.99} &= \dfrac{12}{100} \\ \text{X} &= $1.80 \end{split}\end{equation}$	$$1.80 + $14.99 = $16.79$
   B	40″ flat screen TV	$699.00
   C	Tent	$168.79
   D	Drill and bit set	$248.99
   E	Shoes	$79.98
