Answer:
The Science Center charge less than the Dino Discovery museum for more then 10 students
Step-by-step explanation:
Let us assume that the number of students are x .
Let us assume that the total charge for x students be y.
As given
Mrs. Williams is deciding between two field trips for her class.
The Science Center charges $120 plus $5 per student.
Than the equations becomes
y = 120 + 5x
The Dino Discovery Museum simply charges $7 per student.
y = 7x
Than
Therefore the Science Center charge less than the Dino Discovery museum for more then 10 students.
