James can make a beret from 3 spools of yarn. If he has 12 spools of red yarn, 15 spools of black yarn, and 6 spools of blue yarn, how many berets can he make?
Let's think: First find the total number of spools of yarn James has: 12 spools + 15 spools + 6 spools = 33 spools. Then divide that number by the number spools each beret needs: 33 spools / 3 spools / beret = 11 berets.. The answer is: 11.

There are 350 trees in the park, 70% of which are pine trees. How many are not pine trees?
Let's think: There are 350 x 70 / 100 = 245 pine trees. Therefore, 350 - 245 = 105 trees are not pine trees.. The answer is: 105.

Adam needs a new laptop and has two choices. The first laptop is $500, and the second laptop is 3 times as costly as the first laptop. How much would Adam have to spend if he decides to buy both?
Let's think: The second laptop costs $500 * 3 = $1500. Adam needs to spend $1500 + $500 = $2000 for both.. The answer is: 2000.

Betty picked 16 strawberries. Matthew picked 20 more strawberries than Betty and twice as many as Natalie. They used their strawberries to make jam. One jar of jam used 7 strawberries and they sold each jar at $4. How much money were they able to make from the strawberries they picked?
Let's think:
Matthew picked 16 + 20 = 36 strawberries. Natalie picked 36 / 2 = 18 strawberries. All together, they have 16 + 36 + 18 = 70 strawberries. They can make 70 / 7 = 10 jars of strawberries. They earn 10 x $4 = $40 from the strawberries they picked.. The answer is: 40.
