Cindy puts in 10 cents x 5 = 50 cents. Eric puts in 3 x 25 cents = 75 cents. Garrick puts in 8 x 5 cents = 40 cents. Ivy puts in 60 x 1 cent = 60 cents. After Eric pulls out a quarter, he has still left in the pond, 75 - 25 = 50 cents. Together, they put into the pond, this amount of money, 50 + 50 + 40 + 60 = 200 cents.
The answer: 200

Reasoning and answer: Marie has 4 x 20 = 80 stamps from her notebooks. And she has 2 x 50 = 100 stamps from her binders. So she has a total of 80 + 100 = 180 stamps. Marie decided to keep 180 x 1 / 4 = 45 stamps only. Therefore, she can give away 180 - 45 = 135 stamps.
The answer: 135
