PLEASE HELP ASAP Three friends entered a contest to count the number of jelly beans in a jar. The table shows their guesses of the number of jelly beans in the jar. There were actually 950 jelly beans in the jar.

Which statements are true?

Name Number guessed
Brandon 991
Li Mei 939
Jodi 976

Choose exactly two answers that are correct.

B.Jodi had the highest percent error.

A. and D. For A multiply 950 by .012 and you get 11 (rounded) meaning she was off by about 11, which she was. You can instantly rule B out because Brandon was the furthest off not Jodi. For C multiply 950 by .26 and you get 247, she was not off by 247, she was off by 26, so that's wrong. And for D multiply 950 by .043 and you get 41 (rounded) which means he was off by 41, which he was. And there's your answer A and D are true :) Hope this helped
