Question

The value of facebook shares changed from $27.10 on the 8th June 2013 to $30.01 on the 15th June. How do you calculate the percentage change?

Answer 1

The percentage change was 10.7% rounded to the nearest 1/10th percent.

Explanation:

The formula for calculating the percentage change of something is:

`p = (N - O)/O * 100` where `p` is the percent change, `N` is the new value and `O` is the old value, In this problem we are told the old value is $27.10 and the new value is 30.01 so we can substitute these for `O` and `N` in the formula and calculate the percentage change:

`p = (30.01 - 27.10)/27.10 * 100`

`p = 2.91/27.10 * 100`

`p = 291/27.10`

`p = 10.738` or `10.7` rounded to the nears 1/10 percent.
