July 6 - August 6 - September 6 -- that's 2 months elapsed, not three. Five people working for 2 months is 10 person-months. Apple paid them just under $52,000, none of which was guaranteed. They had to pay whatever taxes are appropriate for their jurisdictions. I'd say Apple got an amazing bargain.
Just because Apple got an amazing bargain doesn't mean the payout for them won't be great as well.
