Question: Every day Janet spends 8 minutes looking for her keys and another 3 minutes complaining after she finds them. If Janet stops losing her keys, how many minutes will she save every week?
Answer: First find the total time Janet spends looking for her key and complaining each day: 8 minutes / day + 3 minutes / day = 11 minutes / day. Then multiply that number by the number of days in a week to find the weekly time spent: 11 minutes / day * 7 days / week = 77 minutes. The answer is 77.

Q: Josephine receives a bill from the hospital for 5000$. 50 percent of the bill is for medication. 25 percent of the remaining bill is for overnight stays, and 175$ is for food. The rest of the bill is for the ambulance ride. How much did the ambulance ride cost?

Question: Jaden had 14 toy cars. Then he bought 28 cars from the toy store and got 12 cars for his birthday. Jaden gave 8 of the toy cars to his sister and 3 to his friend Vinnie. How many toy cars does Jaden have left?
Answer: Jaden had a total of 14 cars + 28 cars = 42 cars after buying from the toy store. His total then increased to 42 cars + 12 cars = 54 cars on his birthday. Jaden then had 54 cars - 8 cars = 46 cars after giving 8 to his sister. Finally after giving his friend, Vinnie, a few cars Jaden had 46 cars - 3 cars = 43 cars left. The answer is 43.
[Question]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?
[Answer]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.
