Question

Mrs. Williams is deciding between two field trips for her class. The Science Center charges $80 plus $5 per student. The Dino Discovery Museum simply charges $7 per student. For how many students will the Science Center charge less than the Dino Discovery Museum charges?

Answer 1

More than 40 students

Explanation:

Let x be the number of students .

Given : Mrs. Williams is deciding between two field trips for her class. The Science Center charges $80 plus $5 per student.

i.e. Total cost : 80+5x (1)

The Dino Discovery Museum simply charges $7 per student.

i.e. Total cost : 7x (2)

The inequality that shows Science Center charge less than the Dino Discovery Museum charges will be :-

80+5x<7

Subtract 5x on both sides , we get

80<2x

Divide both sides by 2 , we get

40<x

Hence, for more than 40 students the Science Center charge will less than the Dino Discovery Museum charges.
