In that case, I don't actually know if they specifically wanted to refund the 20k, or the money minus the money returned? Right?
Generally speaking, if you didn't make any money and didn't lose much, you'll get a principal refund, and those who are willing to continue will continue. That's deducting the returned portion. If 60,000, crossed out 30,000, each person was refunded 10,000. Now you take over, then you refund another 10,000 per person is it. If each person is refunded another 20,000, that's actually 10,000 they're out, and now they're making 10,000 more. If it is the case of profit, can share so much profit that's just, now the partnership is certainly not earned money, then they can not ask for more points. Can only be refunded according to the actual out of how much.
In fact, if it is a loss, it should be refunded even less. But in general, if you are a friend, you don't care about the hundreds or thousands of dollars if you don't lose a lot of money. After all, this first time to pay for the time and effort is also money, really want to let you a person from scratch, you have to be more than that I'm afraid that hundreds and thousands of dollars.
