Cristina, John, Clarissa and Sarah want to give their mother a photo album for her birthday. Cristina brings 7 photos, John brings 10 photos and Sarah brings 9 photos. If the photo album has 40 slots available, how many photos does Clarissa need to bring in order to complete the photo album?
Let's think: Excluding Clarissa, there are 7 + 10 + 9 = 26 photos. Clarissa needs to bring 40 – 26 = 14 photos to complete the photo album.. The answer is: 14.

Calvin signed up for a gym training service to lose some pounds. If he weighed 250 pounds to start with and lost 8 pounds every month during the training sessions, what's his weight after one year?
Let's think: Since Calvin loses 10 pounds every month, his total weight loss after one year is 12 * 8 = 96 pounds. Calvin weighs 250 - 96 = 154 pounds after a year of hitting the gym.. The answer is: 154.

Julia has a parrot and a rabbit. She buys food for both of the animals for $30 in total a week. Julia has the rabbit for 5 weeks, and the parrot for 3 weeks. How much money did Julia already spend on food for her animals, if the weekly cost of the rabbit food is $12?
Let's think: If the rabbit food costs $12 a week, then the parrot food costs $30 - $12 = $18 a week. Julia has the parrot for 3 weeks, so she spent 3 weeks * $18 / week = $54 on her. The rabbit is her only for 5 weeks, so she spent 5 weeks * $12 / week = $60 on him. In total, Julia spent $54 + $60 = $114 on food for her animals.. The answer is: 114.

Kyle is 5 years older than Julian. Julian is 20 years younger than Frederick. Frederick is 2 times older than Tyson. If Tyson is 20, how old is Kyle?
Let's think:
Frederick is 20 * 2 = 40 years old. Julian is 40 - 20 = 20 years old. Kyle is 20 + 5 = 25 years old.. The answer is: 25.
