I broke a persons phone. Do ipay?

I've known this kid for only about two weeks. He has an iphone 5c. I accidentally dropped his phone and now it won't turn on. I feel obligated to pay for the phone but how much? I feel around $200 but i'm worried if that too much or too little.

As a rule, you owe the replacement cost of a comparable item. So look up what an average, reasonable price for a 5c in good condition is and offer that as a minimum.

A 5C is about $100. The prices dropped because it's quite old. Get them a decent phone, if you're willing to spend $50 more, that'll make up for it.
