Betty is growing parsnips in her vegetable garden. When the parsnips are grown, they are harvested and bundled into boxes that can hold up to 20 parsnips each. Each harvest, three-quarters of the boxes are full, and the remaining boxes are half-full. She gets an average of 20 boxes each harvest. How many parsnips does Betty grow in an average harvest? Give the rationale and then the answer.
Let's think step by step. If three - quarters of the boxes are full, then 1 – ¾ = ¼ of the boxes are half - full. On average, each harvest therefore has 20 boxes * 0.25 = 5 boxes that are half - full. This leaves 20 total boxes – 5 half - full boxes = 15 full boxes. Half - full boxes hold 20 parsnips / 2 = 10 parsnips each. In total, the half - full boxes, therefore, hold 5 boxes * 10 parsnips = 50 parsnips. The full boxes hold a total of 15 boxes * 20 parsnips = 300 parsnips. So Betty harvests a total of 50 + 300 = 350 parsnips in an average harvest.. The answer is: 350.

Alice made 52 friendship bracelets over spring break to sell at school. It only cost her $3.00 in materials to make these bracelets. During the break, she gave 8 of her bracelets away. Back at school, she sells all of the remaining bracelets at $0.25 each. How much profit did she make (money earned after paying initial costs) on the sale of her bracelets? Give the rationale and then the answer.
Let's think step by step. She made 52 bracelets but gave 8 away so she had 50 - 8 = 44 bracelets left. She sold 44 bracelets at $0.25 each for a total of 44 * .25 = $11.00. She made $11.00 but she spent $3.00 on the supplies. So her profit would be 11 - 3 = $8.00.. The answer is: 8.

Milo is making a giant loaf of bread, and the recipe calls for pounds of eggs instead of telling him the number. He needs 6 pounds in total. He looks up online that an egg weighs 1/16 of a pound. If he needs 6 pounds of eggs, how many dozen should he buy? Give the rationale and then the answer.
Let's think step by step. If one egg weighs 1 / 16 of a pound then 1 pound will be made up of 1 / (1 / 16) = 16 eggs. One pound of eggs is 16 eggs so 6 pounds is 6 * 16 = 96 eggs. One dozen is 12 eggs so 96 eggs will make 96 / 12 = 8 dozens.. The answer is: 8.
