Question

Puthina Unge bought a new Compaq computer system on sale for $1,960. It was advertised as 30% off the regular price. What was the original price of the computer?

Answer 1

Let P = original price

 

30% discount of P is 0.30P

 

Sale price is $1960

 

P - 0.30P = $1960

 

P(1 - 0.30) = $1960

 

0.70P = $1960

 

P = $1960/0.70 = $2800

 

Te original price was $2800.
