FIRST CORRECT ANSWER GETS BRAINLIEST, THANKS, AND FIVE STAR.

CDs R Us sells books on tape and on CD. Tapes sell for $10 and CDs sell for $15.Shayna purchased 16 items and spent a total of $220. What did Shayna purchase?

22 tapes

Step-by-step explanation:

that answer could be wrong however, it wasn't specified if he bought a mixture of both items or just one .

also if you had the answer choices that could help a little

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.
