Answer:
B. 7
Step-by-step explanation:
Let x represent number of passenger at the 6th stop.
We have been given that Leah predicts that an average of 5 passengers will board the bus at each of the 6 stops along her route.
Total number of passenger on Leah's route would be [tex]5\times 6=30[/tex].
Now, we will add number of passenger on each stop and equate with 30 to solve for x.
[tex]3+7+5+6+2+x=30[/tex]
[tex]23+x=30[/tex]
[tex]23-23+x=30-23[/tex]
[tex]x=7[/tex]
Therefore, there will be 7 passenger at the 6th stop.
