A class has $90 to spend on a field trip. The field trip costs $2.50 per person and there will be 5 chaperones on the trip. One student used the inequality mc021-1.jpg to find x, the number of students that the field trip budget could accommodate. Which best describes the error in the student’s inequality? The expression representing the cost should be mc021-2.jpg. The expression representing the cost should be mc021-3.jpg. The inequality symbol should be mc021-4.jpg instead of > since up to and including $90 may be spent. The inequality symbol should be mc021-5.jpg instead of > since less than or equal to $90 may be spent.

Answer:
Instead of greater than, the inequality symbol should be greater than or equal to.
Step-by-step explanation:
We know the variable x represents the number of students. We also know there are 5 chaperones attending; this makes x+5 the total number of people attending.
It costs $2.50 per person; this means we multiply the number of people, x+5, by 2.50:
2.50(x+5)
The class has $90 to spend; this means they can spend up to and including $90. This gives us
90 ≥ 2.50(x+5)
