Question

I JUST BOUGHT A NEW COMPUTER FOR $1908.00, INCLUDING 6% SALES TAX. WHAT WAS THE ORIGINAL PRICE OF THE COMPUTER BEFORE THE 6% SALES TAX WAS ADDED

Answer 1

Given:

I JUST BOUGHT A NEW COMPUTER FOR $1908.00, INCLUDING 6% SALES TAX.

That is, the total cost is

Let the item's original cost be represented by x

The total sales tax formula is

`Total\text{ s}ales\text{ tax}=item\text{ cost}* sales\text{ tax}`

Where

`sales\text{ tax}=6\%=(6)/(100)=0.06`

Total sales tax will be

`=x*0.06=0.06x`

To find the total cost, the formula is

`\begin{gathered} Total\text{ cost}=Item\text{ }cost+Total\text{ sales tax} \\ 1908.00=x+0.06x \\ 1908.00=1.06x \\ 1.06x=1908.00 \\ x=(1908.00)/(1.06)=\text{ \$1800} \end{gathered}`

Hence, the original cost, x, of computer is $1800
