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

Answer:

x=$1850

Step-by-step 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,

$x-20\%\ \text{of x}=1480\\\\x-\dfrac{20x}{100}=1480\\\\x-\dfrac{x}{5}=1480\\\\\dfrac{4x}{5}=1480\\\\x=\dfrac{1480\times5}{4}\\\\x=\ 1850$

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