Answer 1

Given:

Price of new computer at local store = $1,449

This is 18% less than what it costs at the Brownstone Mall.

To find:

The cost of new computer at the Brownstone Mall.

Solution:

Let x be the cost of new computer at the Brownstone Mall.

According to the question,

$x-18\%\text{ of }x=1449$

$x-\dfrac{18}{100}x=1449$

$x-0.18x=1449$

$0.82x=1449$

Divide both sides by 0.82.

$x=\dfrac{1449}{0.82}$

$x=1767.07317$

$x\approx 1767.07$

Therefore, the cost of new computer at the Brownstone Mall is $1767.07.
