Nigel won $45 but gave some away. His mother gave him $80 more. If now Nigel has $10 more than twice the amount he originally had, how much money did he give away?

Twice the amount Nigel originally had is 2 * 45 = 90 dollars. Now, Nigel has 10 dollars more, meaning that he has 10 + 90 = 100 dollars. Before his mother gave him 80 dollars, he had been left with 100 - 80 = 20 dollars. This means that Nigel gave away 45 - 20 = 25 dollars.
Thus, the answer is 25.
