Answer:
Let's assume
Ms.Meyer used to bring x students for the cost $9 per student
so, total cost = 9x
now, we are given
For ticket cost $6 , she can brings 47 more students
so, total students =x+47
total cost =6*(x+47)
now, we are given total costs are same for both
we get
we can solve for x
Subtract both sides by 6x
Divide both sides by 3
so, Ms. Meyer brings 94 students to theater.........Answer
