Question: Bridgette has 2 dogs, 3 cats, and 4 birds. She gives the dogs a bath twice a month. She gives the cats a bath once a month. She gives the birds a bath once every 4 months. In a year, how many baths does she give?
Answer: Each dog gets 24 baths a year because 2 x 12 = 24. Each cat gets 12 baths a year because 1 x 12 = 12. Each bird averages .25 baths per month because 1 / 4 = .25. Each bird gets 3 baths a year because .25 x 12 = 3. She gives 48 dog baths because 2 x 24 = 48. She gives 72 cat baths because 3 x 12 = 36. She gives 12 bird baths a year because 4 x 3 = 12. She gives 132 baths a year because 48 + 36 + 12 = 96. The answer is 96.
[Question]Ali and Sara ate 80 small apples combined. Ali ate 4 times more apples than Sara. How many apples did Sara eat?
[Answer]Let A be the number of apples Ali ate and S be the number of apples Sara ate. We have: A + S = 80 apples. And: A = 4S. Which means: 4S + S = 80. So: 5S = 80. So the number of apples Sara ate is: S = 80 / 5 = 16 apples. The answer is 16.
Q: Billy's mom sends him to get ketchup. She gives him $10 and tells him to get the best deal on ketchup that he can and to spend all $10 on ketchup. He finds a bottle with 10 oz that cost $1 each. He finds a bottle that costs $2 that contains 16 ounces. He finds a bottle with 25 ounces that costs $2.5. He finds a $5 bottle that contains 50 ounces. Finally, he finds a $10 bottle with 200 ounces. How many bottles of ketchup does he buy?
A: The 10 ounce bottle costs $.1 an ounce because 1 / 10 = .1. The 16 ounce bottle costs $.125 an ounce because 2 / 12 = .125. The 25 ounce bottle costs $.125 an ounce because 2.5 / 20 = .125. The 50 ounce bottle costs $.1 an ounce because 5 / 50 = .1. The 200 ounce bottle cost $.05 an ounce because 10 / 200 = .05. The 200 ounce bottle is the cheapest per ounce because .05 < .08 < .1 < .125. He buys 1 bottle of ketchup because 10 / 10 = 1. The answer is 1.
