Kelly and her friends started a project called Lemonade for Lions. Every Saturday, they sell lemonade to raise money for lion conservation. Last Saturday, they sold 34 cups of lemonade and had 21 cups of lemonade left over. Let c represent how many cups of lemonade Kelly and her friends had to start. Which equation models the problem?

Step-by-step explanation:

7

step-by-step explanation:

the answer would be 7

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
