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.

Answer the following question.
Shonda is throwing an Easter egg hunt for her 2 kids and their 10 friends. She is also supplying enough eggs for herself and the 7 other adults there to find eggs as well. If there are 15 Easter egg baskets for everyone to share and each ends up holding 12 Easter eggs, when they equally distribute all of the Easter eggs to everyone, how many eggs does each person get?
Step-by-step reasoning process: There are 15 Easter egg baskets with 12 Easter eggs in them, 15 x 12 = 180 Easter eggs. There are 7 adults + Shonda (1) + 2 of Shonda's kids + 10 of their friends = 20 people at the Easter egg hunt. There are 180 Easter eggs for 20 people, 180 / 20 = 9 Easter eggs each for everyone.
The answer is 9.
