Question

If Nintendo had sold 12.2 million games in March and they had thought that they had sold 20.9 million how off was there percent error?

Answer 1

First let's calculate the absolute error by subtracting both values:

`20.9-12.2=8.7`

So the absolute error is 8.7 millions.

Now, in order to find the percent error, we just need to divide the absolute error by the number of games sold:

`(8.7)/(12.2)=0.7131=71.31\text{\%}`

So the percent error is 71.31%.
