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?
Let's be accurate as possible. Think before you answer.
25
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.

.

Therefore, the answer is 25
