6x + 3y < 45 (total cost of all food must be less than $45)
x ≥ 4 (at least 4 friends want wings)
y ≥ 0 (can serve any number of burgers, including zero)
Sara is serving wings and burgers at her party. Wings cost $6.00 per serving and burgers are $3.00 each. Sara knows that at least 4 of her friends want wings. Sara must spend less than $45.00.
If x represents the number of wing servings and y represents the number of burgers, which system of inequalities could be used to determine how many of each kind of food Sara can serve?

The sum of x and y is greater than 0. When y is subtracted from x, the difference is less than or equal to 0. Which system of inequalities could you use to solve for x and y?
x + y > 0
x - y ≤ 0
x - y ≤ 0
