[Question]An amoeba reproduces by fission, splitting itself into two separate amoebae. An amoeba reproduces every two days. How many days will it take one amoeba to divide into 16 amoebae?
[Answer]The amoeba will divide into 1 * 2 = 2 amoebae after 2 days. The amoeba will divide into 2 * 2 = 4 amoebae after 4 days. The amoeba will divide into 4 * 2 = 8 amoebae after 6 days. The amoeba will divide into 8 * 2 = 16 amoebae after 8 days. The answer is 8.
Q: Lana and her friends go to a theater on the weekend to watch a new play Joan told them was live. When they arrived, Lana saw 100 cars in the front parking lot. She saw two times more vehicles at the back than there were in the front parking lot. If the total number of cars at the end of the play was 700, how many more cars packed into the parking lot during the play?
A: The number of cars in the back parking lot was 100 * 2 = 200 times more than those in the front parking lot. There were 200 + 100 = 300 cars in the back parking lot. A total of 300 + 100 = 400 cars were present before the play began. The total number of cars that parked in the theater during the play is 700 - 400 = 300 cars. The answer is 300.
Question: Jack will have ten times more handball trophies than Michael has right now in three years. If Michael has 30 trophies right now, and the number of his trophies increases by 100 in three years, what's the total number of trophies they'll have altogether after three years?
Answer: In three years, Michael will have 30 + 100 = 130 trophies. If Michael has 30 trophies now, Jack will have 10 * 30 = 300 in three years. Altogether, Jack and Michael will have 300 + 130 = 430 handball trophies in three years. The answer is 430.

A: She has 5 grandchildren 4 children so she needs 5 + 4 = 9 stockings. The stockings are $20.00 each and currently 10% off so that's 20 * .10 = $2.00 off. The stockings are $20.00 with a $2.00 discount so they are each 20 - 2 = $18.00. The stockings are now $18.00 and she needs 9 so that's $162.00. She also wants to monogram each stocking at $5.00 per stocking so that's 9 * 5 = $45.00. The stockings are $162.00 and the monogramming will cost $45.00 so the stockings will cost 162 + 45 = $207.00. The answer is 1035.
