To find how many people went to the mall, count each x
At 0 trips, there are 2 xs, so<u> 2</u> people had 0 trips to the mall
At 1 trip, there are 0 xs, so <u>0</u> people had 1 trip to the mall
At 2 trips, there are 10 xs, so <u>10 </u>people had 2 trips to the mall
At 3 trips, there are 7 xs, so <u>7</u> people had 3 trips to the mall
Add up all the xs
2+0+10+7=19
19 people in all
-10+2b+8
-2+8b+8
Calculated sum
-2+8b
