Question

You save $220 on your new laptop because you bought it online if this was a 20% savings of the original price by the original cost of the laptop

Answer 1

Let x represent the original price of the laptop. If $220 represents 20% of the original price, then x is to 100% as 220 is to 20%:

`(x)/(100)=(220)/(20)`

Solve for x:

`x=(220)/(20)*100=1100`

Therefore, the original cost of the laptop was $1100.
