Ineed . semir, sarah, and sungso decided to raise money for a local homeless shelter by working in a local deli. the deli agreed to donate to the shelter a portion of the profits from each meal the three sold. semir sold 3 times as many meals as sarah. sungso sold 2 more meals than sarah. the three decided to participate in a walkathon to raise additional money for the shelter. sarah walked 5 miles less than twice the number of miles that semir walked. they each collected $18 in pledges for every mile they walked. a. let n represent the number of miles semir walked. write an expression for the number of miles sarah walked and an expression for the amount of money sarah collected in pledges

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.
