Q: A frog lays her eggs over a series of 4 days. The first day she lays 50 eggs. The second day, she doubles her production of eggs. The third day she lays 20 more than the second day, and the last day she doubles the first three days total. How many eggs did the frog lay over the span of the 4 days?
A: Day 1:50. Day 2:50(2) = 100. Day 3:100 + 20 = 120. Day 4:2(50 + 100 + 120) = 540. Total:50 + 100 + 120 + 540 = 810 eggs. The answer is 810.

[Question]On Sunday Trey is going to do some chores at home. First, he wants to make a To Do list and count up how many things he has to do that day and how long it should take. He has several items under 'clean the house,' 'take a shower' and then 'make dinner.' In total there are 7 things to do to clean the house; 1 thing to do to take a shower; and 4 things to do to make dinner. If everything on Trey's list takes 10 minutes to do, how many hours total will it take to complete Trey's list?
[Answer]On Trey's list there are 7 + 1 + 4 things to do = 12 things to do in total. Each thing takes 10 minutes to do, so 10 minutes x 12 things = 120 minutes. An hour has 60 minutes in it, so 120 minutes / 60 minutes in an hour = 2 total hours it will take Trey to complete his list. The answer is 2.

Question: John climbs 3 staircases. The first staircase has 20 steps. The next has twice as many steps as the first. The final staircase has 10 fewer steps than the second one. Each step is 0.5 feet. How many feet did he climb?
Answer: The second flight had 20 * 2 = 40 steps. The third had 40 - 10 = 30 steps. So in total, he climbed 20 + 40 + 30 = 90 steps. So he climbed 90 * .5 = 45 feet. The answer is 45.
Q: Holly wants to plant a wall of privacy trees along her fence line. Her fence is 25 yards long. At maturity, the trees she wants to plant will measure 1.5 feet wide. Right now, these trees are on sale for $8.00 apiece. How much will it cost her to plant a row of the trees to run the length of her fence?
A:
3 feet are in 1 yard and her fence is 25 yards long so her fence is 3 * 25 = 75 feet long. At maturity these trees will measure 1.5 feet and she needs them to run along her 75 - foot fence so she needs 75 / 1.5 = 50 trees. The trees cost $8.00 apiece and she needs 50 so 8 * 50 = $400.00 worth of trees. The answer is 400.
