Question

Ms. Ellis expected 50 families to attend parent teacher conference but 60 families attended. What is the percent error?

Answer 1

Answer:

20%.

Step-by-step explanation:

That is  (60 - 50) / 50

= 10/50

= 1/5

To convert to a percent we multiply by 100:

= 20%.

Answer 2

I think it will be 10% because you invited 50 right? And 60 atended or was it 60 and 50 atended? Well either way I think it’s 10%
