Nalani had two female dogs that were expecting and after a month gave birth to 10 puppies each. She then sold 3/4 of the puppies after they came of age, each at $200. Calculate the total amount of money she received from the sale of the puppies.
Let's think: If the two expectant dogs gave birth to 10 puppies each, the total number of puppies Nalani had is 10 + 10 = 20. When they came of age, Nalani sold 3 / 4 of the dogs, a total of 3 / 4 * 20 = 15 dogs. If each dog sold for $200, Nalani received 15 * 200 = $3000 from the sale of the dogs.. The answer is: 3000.

Rachel is an artist. She posts a speed painting video each week on her Instagram account to promote her work. To save time, she paints and records 4 videos at a time. It takes her about 1 hour to set up her painting supplies and her camera. Then she records herself painting for 1 hour per painting. She takes another 1 hour to clean up. Each video takes 1.5 hours to edit and post. How long does it take Rachel to produce a speed painting video?
Let's think: Rachel spends 1 + 1 = 2 hours setting up and cleaning up. She paints for 1 hour x 4 paintings = 4 hours. Then she edits 1.5 hours x 4 videos = 6 hours. She spends 2 + 4 + 6 = 12 hours to make 4 videos. So Rachel spends 12 / 4 = 3 hours on each video.. The answer is: 3.

Normally Ann can frost a cake in 5 minutes. However, today she has a sprained wrist and it takes her 8 minutes to frost a cake. How much longer would it take her to frost 10 cakes with her sprained wrist?
Let's think: Normally, it would take her 5 * 10 = 50 minutes. With her sprained wrist it will take her 8 * 10 = 80 minutes. 80 - 50 = 30 more minutes.. The answer is: 30.

8 * 60 = 480 minutes are in the next 8 hours. Abigail builds 480 / 30 = 16 fences. Abigail will have built 10 + 16 = 26 fences in total.. The answer is: 26.
