Question

Last year’s computer models are discounted 20%. What was the original price to the nearest dollar of a computer that now costs $1,480?

$1,184

$1,500

$1,510

$1,850

Answer 1

x=$1850

Explanation:

Let the original price of the computer model is x.

Last years discount is 20%

We need to find the original price if the computer now costs $1480.

ATQ,

`x-20\%\ \text{of x}=1480\\\\x-(20x)/(100)=1480\\\\x-(x)/(5)=1480\\\\(4x)/(5)=1480\\\\x=(1480*5)/(4)\\\\x=\$1850`

So, the original cost of the computer model is $1850.
