[Question]Connie redeemed all her arcade tickets today. She spent half of them on a stuffed koala bear. She spent 10 tickets on a pair of earbuds. She spent another 15 tickets on glow bracelets. How many tickets did Connie redeem today?
[Answer]Connie spent 10 tickets on earbuds + 15 tickets on glow bracelets = 25 tickets.

Question: Jolene and Phil have four children, each with the same birthday. They gave birth to their first child exactly 15 years ago. They gave birth to their second child exactly one year after the birth of their first child. They gave birth to their third child on the fourth birthday of their second child. Two years after the birth of their third child, they gave birth to their fourth child. How old, in years, is their fourth child?
Answer: Their 1st child was born 15 years ago, and therefore is 15 years old. Their 2nd child was born 1 year after their 15 - year - old child, and therefore is 15 - 1 = 14 years old. Their 3rd child was born 4 years after their 14 - year - old child, and therefore is 14 - 4 = 10 years old. Their 4th child was born 2 years after their 10 - year - old child, and therefore is 10 - 2 = 8 years old. The answer is 8.
[Question]Daniel has a collection of 346 video games. 80 of them, Daniel bought for $12 each. Of the rest, 50% were bought for $7. All others had a price of $3 each. How much did Daniel spend on all the games in his collection?
[Answer]On 80 games, Daniel spend 80 games * $12 / game = $960. The rest of the collection is 346 games - 80 games = 266 games. 50% of these games means 50 / 100 * 266 games = 133 games. Daniel bought them for $7 each, so he had to spend 133 games * $7 / game = $931 on them. The other 133 games were bought for $3 each, so they've cost him 133 games * $3 / game = $399. On all games in total Daniel spent $960 + $931 + $399 = $2290. The answer is 2290.
[Question]Toby wants to walk an average of 9,000 steps per day over the next week. On Sunday he walked 9,400 steps. On Monday he walked 9,100 steps. On Tuesday he walked 8,300 steps. On Wednesday he walked 9,200 steps. On Thursday he walked 8,900 steps. How many steps does he need to average on Friday and Saturday to meet his goal?
[Answer]
He needs to walk 63,000 steps in a week because 7 x 9,000 = 63,000. He has 18,100 steps to walk on Friday and Saturday because 63,000 - 9,400 - 9,100 - 8,300 - 9,200 - 8,900 = 18,100. He needs to walk an average of 9,050 on Friday and Saturday because 18,100 / 2 = 9,050. The answer is 9050.
