After rewriting all sets of data from smaller to greater, I found that the last series is the one that is represented by the plot box:
79,86,88,88,92,98,100,106,115,136
Why? Because The median is 95 (like the box)
because the outliers are > 115 (up to 136)
because their is no outlier on the left by the mini value of 79
You can use elimination to solve systems of equations with 3 equations. I know how to solve systems of equatons with 3 equations, but I use a different process, I don't know how to use the elimination method.
The math I used is probably not the quickest way, but for me, the easiest.
25*5=125 25+20=45 45*7=315 125+315=440 25*4=100 440+100=540 5+7+4=16
B is your answer.
