Direct Proof is the answer.
Answer:
Part A)

Part B)

Step-by-step explanation:
We will let <em>t</em> represent the total number of t-shirts printed.
We are charged an initial fee of $25. So, for our linear model, our constant is 25. And each t-shirt printed costs an additional $8. So, for <em>t</em> t-shirts, it will cost an additional 8<em>t</em> dollars.
Part A)
So, from the above information, we can write the following function:

Where <em>C(t)</em> is the total cost for <em>t</em> shirts.
The 25 represents our initial fee and the <em>8t</em> represents the cost for <em>t</em> t-shirts.
Part B)
So, if we have a team of 35 members, we will need 35 t-shirts.
Then the total cost will be given by:

So, it will cost a total of $305.
