The answer is A, because she can’t buy more than 22 shirts.

Let’s set up an inequality. We know that she spent $75 on a jacket. Each shirt costs $10.

X= # of shirts bought

75 + 10x <= 300
Subtract 75 from both sides.
10x <= 225
Divide both sides by 10.
x<= 22.5

Therefore she can only buy 22 shirts.
