Answer the following question.
There are 350 trees in the park, 70% of which are pine trees. How many are not pine trees?
Step-by-step reasoning process: There are 350 x 70 / 100 = 245 pine trees. Therefore, 350 - 245 = 105 trees are not pine trees.

Answer the following question.
The spacecraft Gibraltar is a mountain-sized intergalactic vehicle for transporting equipment, building materials, and families to establish colonies on far-away planets. At full capacity, the vehicle can carry 300 family units with four people per family. The space flight is expected to take years, and it is expected that the size of families will grow during the space voyage. Therefore, when the spacecraft leaves the earth, it will carry 100 people less than one-third of the ship's capacity. How many people will be on the ship to start the journey?
Step-by-step reasoning process: The full capacity of the ship is 300 * 4 = 1200 people. One - third of capacity is 1200 / 3 = 400 people. 100 less than one - third capacity is 400 - 100 = 300 people.
The answer is 300.

Answer the following question.
Mark plants some strawberries in his backyard. Every month, the number of strawberry plants doubles. After 3 months, Mark digs up 4 strawberry plants and gives them to his friend. If he still has 20 strawberry plants, how many did he initially plant?
Step-by-step reasoning process: First, add the 4 plants Mark gave away to the 20 he has left: 4 + 20 = 24. Then divide this number by 2 to find how many plants Mark had after two months: 24 / 2 = 12. Then divide that number by 2 to find how many plants Mark had after one month: 12 / 2 = 6. Finally, divide that number by 2 to find out how many plants Mark initially planted: 6 / 2 = 3.
The answer is 3.
