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

Solution:

Given:

$\begin{gathered} In\text{ 2003, the price was \ }16,500 \\ In\text{ 2021, the price was \ }17,300 \end{gathered}$

The increase in price from 2003 to 2021 is;

$\begin{gathered} Increase=17300-16500 \\ Increase=\text{ \ }800 \end{gathered}$

The percent increase is gotten by;

$\begin{gathered} Percent\text{ increase}=\frac{increase}{initial\text{ value}}\times100\text{ \%} \\ Percent\text{ increase}=\frac{800}{16500}\times100\text{ \%} \\ Percent\text{ increase}=4.848484848484 \\ Percent\text{ increase}\approx4.85\text{ \%} \end{gathered}$

Therefore, the percent increase is approximately 4.85%
