Which box plot represents the data? 135, 149, 156, 112, 134, 141, 154, 116, 134, 156

To get the box plot we begin by arranging the data in ascending order:
135, 149, 156, 112, 134, 141, 154, 116, 134, 156
rearranging we get:
112,116, 134, 134, 135, 141, 149, 154, 156, 156
then:
Lower value=112
Q1=134
Median=(135+141)/2=138
Q3=154
Largest value=156

The second figure is the correct figure.

X= 2 he can buy 2 packs of cards for $12 and an action figure for $3 so he would spend $15 in total plus the free poster
