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? Give the rationale and then the answer.
Let's think step by step. 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.

Bob was creating a math test for an online platform. He created 13 questions in the first hour. Bob then doubled his rate for the second hour, and doubled his second hour rate for the third hour. How many questions did Bob create in the three hours? Give the rationale and then the answer.
Let's think step by step. First hour: 13. Second hour:13(2) = 26. Third hour: 26(2) = 52. Total:13 + 26 + 52 = 91 questions.. The answer is: 91.

Let's think step by step. From Monday to Friday, Iggy runs a total of 3 + 4 + 6 + 8 + 3 = 24 miles. Iggy runs for a total of 24 * 10 = 240 minutes. Since there are 60 minutes in an hour, Iggy runs for a total of 240 / 60 = 4 hours.. The answer is: 4.
