Question

During a clearance sale, an electronic store sold a Blu-ray player for S291. If the items on sale were discounted by 25%, find the original retail price of the Blu-ray player.

Answer 1

The final price is $291.

We know that a 25% discount has been applied.

Then, if P is the original price, we can write the equality as:

`\begin{gathered} 291=P-0.25P \\ 291=(1-025)P \\ 291=0.75P \\ P=(291)/(0.75) \\ P=388 \end{gathered}`

The original retail price is $ 388.
