The answer is 15 shirts.
35+25=60 dollars, so George needs to make more than that in order to make a profit.
If I recall, the following of the question is it costs 5.80 to make a shirt and he charges 10.
5.8*15=87 , 10*15=150. 150-87=63. He makes a 3 dollar profit, but it's still considered profit.
