An exercise class costs $9 per class. seven students are planning to take 12 classes. how much will the students pay in all.

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 theaterAnswer
