The drama club is planning a field
Inessa [10]

Answer:

\frac{2}{3}s+8=48.

Step-by-step explanation:

  • If we indicate the amount of students in the drama club as"s", we know that \frac{2}{3}s is attending to the trip.
  • We also know that there are will be 8 teachers in the trip as well.
  • If the total amount of persons that will go on the trip reachs 48, which is the sum of 8 teachers and the \frac{2}{3}s of the students: \frac{2}{3}s+8=48.
  • Then, the equation that describes the situation is \frac{2}{3}s+8=48. If we subtract 8 from both sides of the equation, and then we have \frac{2}{3}s=40, which means that s=60.
