I interpreted the question to have one shipping cost, independent of number of shirts ordered:
 
   35c + s = 337.50
   56c + s = 516
 
In this case, the cost per shirt (c) and shipping costs (s) can be found.
c represents the cost per shirt
s represents the s&h per shirt
 
35c + 35s = 337.50
56c + 56s = 516
 
Can you solve the system?
