Profit = 5,000
Step-by-step explanation:
Well this question isn't very clear since it didn't state what the original cost for one iphone is. I think they are assuming one iphone to be 200 dollars or the sold amount, but this information is not directly stated. Anyways....
How much they make 100x200 = 20,000
Expenses 100(200-50) = 15,000
Profit 20,000 - 15,000 = 5,000
