Question

George runs an outlet where he sells personalized t-shirts. he spends $35 to rent the printing machine and $25 for phone service each month.

Answer 1

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.
