PLZZZ HELP DUE IN 10 MINUTES. PLZZZ.

15. Scarlett estimated that there were 50 pieces of candy left in her Halloween basket. When she counted,
there was actually only 46 pieces left. What was her percent error?

Answer 1

Answer: 8% Error

Explanation:

Lets go ahead and change the equation to a format that we're more familiar with.

Original:

50 -> 46

But what's easier is if we are working with 100's because of 100% right?

So lets do this.

100 -> 92

All I did was multiply both by 2 to get 100 to 92. Now it's easier to determine because of what we're looking at. 100-92 is 8% which also makes 50 to 46 an 8% error because of the symmetry between both equations. Enjoy!
