Answer:
3
Explanation:
She has no more to spend than $55, which means the starting equation is:
x<=55.
She wants to buy ONE pair of pants, which means that you have to subtract 55 by 19.95.
55-19.95=35.05;
x<=35.05;
Each t-shirt costs 9.5 each, which means the equation is now
9.5x<=35.05
Which, if you divide by 9.5 on both sides, is
x<=3.68947368.
So, at most, she can buy 3 shirts.
