Dean buys 25 stickers on Monday and 17 on Tuesday, On Wednesday he gives \( \frac{1}{6} \) of his stickers to Jack. How many does he have left?

Dean starts with 25 stickers from Monday and adds 17 stickers from Tuesday, giving him a total of \( 25 + 17 = 42 \) stickers. On Wednesday, he gives away \( \frac{1}{6} \) of his stickers, which is \( \frac{1}{6} \times 42 = 7 \) stickers. Now, to find out how many stickers Dean has left, we subtract the 7 stickers he gave to Jack from his total: \( 42 - 7 = 35 \) stickers. So, Dean has 35 stickers left.
