ANSWER
C. 50 > x + 12.50
Step-by-step explanation
We have that the price of each t-shirt is the same and the pair of shorts cost $12.50.
Let the price of the t-shirts John bought be x.
We have that John did not speand more than $50.
This means that, if we add the prices of the t-shirts and the pair of shorts, it must be less than $50.
Therefore, the inequality is:
x + 12.50 < 50
This is not among the options, but we can rewrite it as:
50 > x + 12.50
That is the answer. Option C.
