During the Arkansas and Texas tech game the Razorback t-shirt shop made $ 215 by selling 5 t-shirts. What is the cost of each t-shirt?
Let's denote the cost of one t-shirt by c. Then the total cost of 5 t-shirts is 5c. 

The shop made $215, so we have 

5c=215. 

Therefore the answer (numeric) is: 

5c=215 => c=215/5 = 43
