1. Jimmy has 987 apples.
2. He gives 20 to his wife.
987 - 20 = 967
3. Then, 3 of his friends each take 10.
967 - 3(10) = 937
4. His friends give him 6 back each
937 + 3(6) = 955
5. He buys 6 apples and then gives 11 to a food place.
955 + 6 - 11 = 950
6. He buys 77 and then donates 66.
950 + 77 - 66 = 961
7. He gets 44 more and then 88 more but then his wife takes 55 and uses 11.
961 + 44 + 88 = 1093
1093 - (55-11) = 1049
Thus, Jimmy has 1,049 apples remaining.
