Morgan estimates that it will take 12 minutes to download a movie from an online movie store. It
actually took 15.5 minutes to download the movie. Find the percent error. Round to the nearest
whole number, if necessary.
First, you subtract the orginal number from the new number. Which means, 15.5 - 12, which is equal to 3.5. Then you take 3.5 and then divide it by 12. Then, multipe it by 100.
