Q: Bob grew corn in his garden and is ready to harvest it. He has 5 rows of corn, and each row has 80 corn stalks. About every 8 corn stalks will produce a bushel of corn. How many bushels of corn will Bob harvest?
A: Bob has 5 rows of corn, each with 80 corn stalks, so he has 5 rows * 80 stalks per row = 400 corn stalks. 8 corn stalks will produce a bushel of corn, so Bob will harvest 400 corn stalks / 8 corn stalks per bushel = 50 bushels of corn. The answer is 50.

Q: Tom's brother is 4 times as old as Tom's dog. If in 6 years, Tom's brother will be 30 years, how old is Tom's dog going to be in six years?
A: If in six years Tom's brother will be 30 years old, he is currently 30 - 6 = 24 years old. Since Tom's brother is 4 times as old as Tom's dog, Tom's dog is 24 / 4 = 6 years old currently. Tom's dog will be 6 + 6 = 12 years old in six years. The answer is 12.

Q: Emily went to the store and bought art supplies for $20 and 2 skirts that cost the same amount of money. She spent a total of $50. How much did Emily pay for each of the skirts?
A:
First, you need to set up the problem with the information given. The cost of the skirts and art supplies must equal $50. Since we know that the cost of the skirts is the same price and that she bought art supplies for $20, we can set up an equation: 2x + 20 = 50, with x being the cost of the skirts. To solve the equation, subtract 20 from both sides, to give you the new equation: 2x = 30. Solve for x by dividing both sides of the equation by 2, 2x / 2 = 30 / 2 gives you x = 15. Therefore, each skirt cost $15. The answer is 15.
