Answer:
3rd option; 3p + 4g is less or equal to 36
Explanation:
Constraint is like a limit. The student can spend at maximum 36 dollars. That means they can spend less than that, so that is why it is less or equal to 36. The reason option three is better than option one is because you are talking about the price; p = # of packages of lined, g = # of packages of graph. To find the total price, you would need to multiply # of packages by the price per package. That is why 3p + 4g is less or equal to 36 is the best option for the student's SPENDING CONSTRAINTS.
