Question

Answer 1

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

$120 + 5x < 7x$

$120 < 7x - 5x$

$120 < 2x$

$\frac{120}{12} < x$

$10 < x$

Therefore the Science Center charge less than the Dino Discovery museum for more then 10 students.
