Final answer:
The profit function f(x) is equal to 15x - 25. Evaluating f(200) gives a value of 2975, which represents the amount of profit made.
Step-by-step explanation:
The profit function f(x) is defined as f(x) = 15x - 25, where x represents the number of T-shirts sold. To find the value of f(200), we substitute x = 200 into the function:
f(200) = 15(200) - 25 = 3000 - 25 = 2975
Therefore, the statement 'It results in 2,975 and means that $2,975 was made in profit' is true.
