Reasoning and answer: He invited 10 friends but he didn't need to cook for 1 of his friends so that left 10 - 1 = 9 friends to cook for. He was cooking 3 burgers per 9 guests so 3 * 9 = 27 burgers. He needed 27 burger buns but 1 guest wouldn't eat the buns so now he needs 27 - 3 = 24. He will need to buy 24 buns and they come 8 to a pack so he needs 24 / 8 = 3 packs of buns.
The answer: 3

The food cost 3 * 50 = $150. So the total cost without equipment rental was 1200 + 150 = $1350. So equipment rental cost 1350 * 2 = $2700. So the total cost was 2700 + 1350 = $4050. That means they made 10000 - 4050 = $5950.
The answer: 5950
