Question

Problem page the price of a notebook has dropped to $3.20 today. Yesterday's price was $3.45 . Find the percentage decrease. Round your answer to the nearest tenth of a percent.

Answer 1

Yesterday's price of notebook = $3.45

Today's price of notebook = $3.20

We have to determine the percentage decrease in the cost of notebook.

Percentage decrease = (Decrease
`/` Old price)
`* 100`

So, percentage decrease =
`(3.45-3.20)/(3.45) * 100`

=
`(0.25)/(3.45) * 100`

= 7.246%

= 7.25%

Therefore, there is 7.25% of decrease in the cost of the notebook.
