Venny spent $15000 on a used car which cost 40% of the original price. What was the original price of the car?
Let's think: Let x be the original price of the car. Then 40% * x = $15000. Thus x = $15000 / 0.4 = $37500.. The answer is: 37500.

In ten years, I'll be twice my brother's age. The sum of our ages will then be 45 years old. How old am I now?
Let's think: Let X be my age now. In ten years, I'll be X + 10 years old. In ten years, my brother will be (X + 10) * 1 / 2 years old. In ten years, (X + 10) + (X + 10) * 1 / 2 = 45. So (X + 10) * 3 / 2 = 45. X + 10 = 45 * 2 / 3 = 30. X = 30 - 10 = 20 years old.. The answer is: 20.

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?
Let's think: 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.

Oshea bought 200 basil seeds. He wants to plant them in planters. He has 4 large planters that can hold 20 seeds each. He also has small planters that can hold 4 seeds each. How many small planters will he need to plant all the basil seeds?
Let's think:
The large planters can hold a total of 4 * 20 = 80 seeds. This will leave Oshea with 200 - 80 = 120 seeds remaining. This means he will need 120 / 4 = 30 small planters.. The answer is: 30.
