Q: Marcia wants to buy some fruit. Apples cost $2, bananas cost $1, and oranges cost $3. If Marcia buys 12 apples, 4 bananas and 4 oranges, what is the average cost of each piece of fruit in dollars?
A: Find the price of each group of fruit. 12 apples * $2 per apple = $24. 4 bananas * $1 per banana = $4. 3 oranges * $4 per orange = $12. $24 + $4 + $12 = $40 in total that was spent. 12 + 4 + 4 = 20 total fruits bought. $40 / 20 fruits = $2 per fruit. The answer is 2.
Question: Jim is a maintenance worker at a pool. Every time someone jumps in the pool, they cause 400 ml of water to splash out and evaporate. Jim has to get everyone out of the pool, clean, and refill it when it gets below 80% full. If the pool holds 2000 L of water, how many times can people jump in the pool before Jim has to clean it?
Answer: First figure out how many liters of water are left in the pool when it's 80% full: 2000L * .8 = 1600 L. Now subtract that amount from the pool's total capacity to find how much water can splash out before Jim has to refill it: 2000 L - 1600 L = 400 L. Now multiply that amount by 1000 to convert it to milliliters: 400 L * 1000 ml / L = 400,000 ml. Finally, divide that amount by the amount that splashes out with each jump to find the number of jumps before pool cleaning: 400,000 ml / 400 ml / jump = 1000 jumps. The answer is 1000.
[Question]Martiza is studying for the citizenship test. There are 60 questions on the test. 30 are multiple-choice and 30 are fill-in-the-blank. It takes her 15 minutes to learn each multiple-choice question and 25 minutes each to learn the fill-in-the-blank questions. How many hours will she need to study before she is ready for the test?
[Answer]The multiple - choice questions will take her a total of 30 * 15 = 450 minutes. The fill - in - the - blank questions will take her a total of 25 * 30 = 750 minutes. The test will take her a total of 450 + 750 = 1200 minutes to study for. Therefore, Martiza will need to study a total of 1200 / 60 minutes = 20 hours. The answer is 20.
