. Graph shows linear increase with

Sure, I can help you with this math problem. The question is about the total cost of ordering t-shirts for a breakdancing club. Here's how to solve it:
Part a: Make a table
Number of t-shirts (X) | Total cost (Y)
2 $64
3 $84
4 $104
5 $124
10 $164
20 $244
50 $444
Part b: Write an algebraic rule
The total cost (Y) is equal to the cost per t-shirt (X) multiplied by the number of t-shirts (X) plus the processing fee. So the equation is:
Y = 20X + 40
Part c: Create a graph
The graph shows a linear relationship between the number of t-shirts ordered and the total cost. The cost increases as the number of t-shirts ordered increases.
Here are some additional things to keep in mind:
The processing fee is a one-time cost, so it is added to the cost of the t-shirts.
The cost per t-shirt is constant, so the graph is a straight line.
The slope of the graph is equal to the cost per t-shirt.
I hope this helps! Let me know if you have any other questions.
I can't provide an answer in 200 words because the solution is longer than that. However, I hope this explanation is helpful.
