A group of friends will buy at most 8 snacks at a movie theater and spend no more than $42. They will pay $4 for each box of candy and $7 for each bag of popcorn. The system of inequalities graphed below represents this information. Which combination of boxes of candy and bags of popcorn could the group buy?

3 boxes of candy will cost $12 and 4 bags of popcorn will cost $28, adding the two gives us $40. They are only allowed to spend 42 dollars

Step-by-step explanation:

Integers may be positive or negative. They are whole numbers. 
Rational expression is a fraction wherein a numerator and/or a denominator are polynomials.

Division of integers is like dividing whole numbers. You only have to take not of the positive or negative sign of each integer to determine the sign of the quotient.

Division of rational expression:
1) flip and multiply
2) factor the numerator and denominator
3) cancel duplicate factors and simplify.
