Question

An iPhone marked for $268 was sold for $334 due to its great popularity to customers. By what percent did the price go up?

Answer 1

To find the percentage of change, first, we have to find the difference between prices.

`334-268=66`

Now, we divide 66 by 268 to know which percentage represents.

`(66)/(268)\approx0.25`

Which is equivalent to 25%.

Therefore, the percentage is 25%, approximately.
