Q: I went to the music shop and there were CDs of The Life Journey for $100, A Day a Life for $50, and When You Rescind for $85 on display. If I bought 3 of each CD to share with my friends, what's the total amount of money I spent in the shop?
A: The total cost of The Life Journey is 3 × $100 = $300. The total cost of When You Rescind is 3 × $85 = $255. The total cost of A Day a Life is 3 × $50 = $150. The total cost for all the CDs is $150 + $255 + $300 = $705. The answer is 705.
Question: Hannah sold 40 pieces of cookies for $0.8 each and 30 cupcakes for $2 each. She used the money to buy 2 sets of measuring spoons for $6.5 each. How much money does she have left?
Answer: Hannah's earnings from the cookies is 40 x $0.8 = $32. Her earnings from the cupcakes is 30 x $2 = $60. Her total earnings for the cupcakes and cookies is $32 + $60 = $92. The cost of 2 sets of measuring spoons is 2 x $6.5 = $13. So, Hannah has $92 - $13 = $79. The answer is 79.
[Question]Ittymangnark and Kingnook are an Eskimo couple living in the most northern region of the Alaskan wilderness. Together, they live with their child, Oomyapeck. Every day Ittymangnark catches enough fish for the three of them to eat for the day and they split the fish equally between the three of them. But after they have split the fish, they give Oomyapeck all of the eyes, who gives two of the eyes to his dog and eats the rest himself. How many fish will each of them be given to eat if Oomyapeck eats 22 eyes in a day?
[Answer]If the dog eats two eyes and Oomyapeck eats 22 eyes, then there are a total of 2 + 22 = 24 eyes. With 2 eyes per fish, 24 eyes represent 24 / 2 = 12 fish. If they split that number of fish equally amongst the three of them, then each of them will be given 12 / 3 = 4 fish to eat. The answer is 4.
Q: Kim's TV uses 125 watts of electricity per hour. She runs it for 4 hours a day. If electricity cost 14 cents per kw/h how many cents does her TV cost to run for a week?
A: She uses 4 hours / day * 125 watts / hour = 500 watt hours / day. That means she uses 500 watt hours / day * 7 days / week = 3500 watt hours / week. This is 3500 watt hours / 1000 watts / kw = 3.5 kw hours. So her TV cost 3.5 kw hours / week * $0.14 / kw hour = $0.49 / week. The answer is 49.
Question: Sam works at the Widget Factory, assembling Widgets. He can assemble 1 widget every 10 minutes. Jack from the loading dock can help assemble widgets when he doesn't have anything else to do. When he helps, they put together 2 complete widgets every 15 minutes. Recently the factory hired Tony to help assemble widgets. Being new to the job, he doesn't work as fast as Sam or Jack. Yesterday Sam worked for 6 hours before he had to leave work early for a dentist appointment. Jack was able to help out for 4 hours before he had to go back to the loading dock to unload a new shipment of widget materials. Tony worked the entire 8-hour shift. At the end of the day, they had completed 68 widgets. How long does it take Tony to assemble a Widget, in minutes?
Answer: Sam completes a widget every 10 minutes. When Jack helps they finish 2 in 15 minutes. Sam has finished 1 widget and has begun working on another one, and Jack finishes the second one at 15 minutes. So it takes Jack 15 minutes to complete a widget. Sam worked for 6 hours yesterday, so he was able to complete 6 hours * 60 minutes per hour / 10 minutes per widget = 36 widgets. Jack worked for 4 hours, so he was able to complete 4 hours * 60 minutes per hour / 15 minutes per widget = 16 widgets. Sam, Jack, and Tony were able to complete 68 widgets together. So of those, Tony personally completed 68 widgets - 36 widgets - 16 widgets = 16 widgets. It took Tony 8 hours to complete those 16 widgets, so he takes 8 hours * 60 minutes per hour / 16 widgets = 30 minutes per widget. The answer is 30.
Q: In a national park, the number of redwoods is 20% more than the number of pines. If there are 600 pines in the national park, calculate the total number of pines and redwoods that are there.
A:
If there are 600 pines, there are 20 / 100 * 600 = 120 more redwoods than pine trees in the national park. In total, there are 120 + 600 = 720 redwoods in the national park. Altogether, there are 720 + 600 = 1320 pines and redwoods in the national park. The answer is 1320.
