Championship t-shirts sell for $22 each.
a. what point(s) must be on the graph for the quantities to be proportional to each other?
b. what does the ordered pair (5, 110) represent in the context of this problem?
c. how many t-shirts were sold if you spent a total of $88?

A.  (1,22), (2,44), (3,66)

B. 5 shirts were bought and the total was $110

C. 4

Step-by-step explanation:

A.

For every 1 increase in the x variable(the first number) the y variable(the second number) increases by 22

B.

The pair represents that he got 5 shirts and that he paid $110. you can check your work by seeing that if yoiu divide 110 by 5 you get the price of the t-shirt; $22

C.

If each shirt is $22 you divide $88 by $22 and get the amount of t-shirts bought; 4
