Answer this question:Brianna started out with a bag of 24 marbles. She lost four marbles through a hole in the bag. Then, she gave away twice as many marbles as she had lost through the hole in the bag. Finally, her dog ate half as many marbles as Brianna had lost through the hole in the bag. How many marbles did Brianna have remaining?
Brianna gave away twice as many marbles as she had lost, or a total of 2 * 4 = 8 marbles. Her dog ate half as many marbles as Brianna had lost through the hole in the bag, or 4 / 2 = 2 marbles. If she started with 24 marbles, then the number of marbles remaining is 24 - 4 - 8 - 2 = 10 marbles.
The answer is 10.

Answer this question:Mother made 2 dozen brownies and placed them on the kitchen counter to cool. Father smelled the brownies, came into the kitchen and ate 8 of them. Then, their daughter, Mooney, wandered into the kitchen and ate 4 of the brownies. The next morning, Mother made another two dozen brownies and added them to those remaining from the day before. After that, how many brownies were on the counter?
Two dozen brownies is 2 * 12 = 24 brownies. After Father ate his 8, there were 24 - 8 = 16 brownies remaining on the counter. After Mooney ate her 4, there were 16 - 4 = 12 brownies remaining on the counter. Mother made a second batch of two - dozen brownies, or 2 * 12 = 24 brownies. After Mother added the second two - dozen, there were 12 + 24 = 36 brownies on the kitchen counter.
The answer is 36.

Answer this question:Jake is watching a new show, and is worried about how much time he has spent watching it. He spent half the day on Monday watching his show, 4 hours on Tuesday watching his show, a quarter of the day on Wednesday watching his show, and he spent half as much time watching the show on Thursday as he had done in total throughout the previous few days. On Friday, he finally finished watching it. If the entire show is 52 hours long, how many hours did Jake watch on Friday?
On Monday, Jake watched 24 hours / 2 = 12 hours. On Wednesday, he watched 24 hours / 4 = 6 hours. So from Monday to Wednesday, he watched a total of 12 Monday hours + 4 Tuesday hours + 6 Wednesday hours = 22 hours. He watched half of this on Thursday, which is 22 hours / 2 = 11 hours. So from Monday to Thursday, he watched 22 + 11 = 33 hours. To finish the show on Friday, he must have therefore watched 52 33 = 19 hours.
The answer is 19.

Answer this question:Uncle Jude baked 256 cookies. He gave 15 cookies to Tim, 23 cookies to Mike, kept some in the fridge and gave the rest to Anna. How many cookies did he put in the fridge if he gave twice as many cookies as he gave Tim to Anna?
He gave twice 15 cookies to Anna which is 2 * 15 = 30 cookies. He gave out a total of 15 + 23 + 30 = 68 cookies. The remainder in the fridge is 256 - 68 = 188 cookies.
