Question: Stephanie is decorating 24 cupcakes for a birthday party, but she needs more candles. She currently has a total of 30 candles. She wants to decorate half of the cupcakes with 1 candle each and the other half of the cupcakes with 2 candles each. How many additional candles does Stephanie need to complete the cupcakes?
Answer with step-by-step thinking: For half of the cupcakes, Stephanie wants to use 1 candle each. Since half of the cupcakes is 24 / 2 and she plans to use 1 candle each for this half of the cupcakes, Stephanie needs (24 / 2) * 1 = 12 candles for this half of the cupcakes. For the other half of the cupcakes, Stephanie wants to use 2 candles. Therefore, she will need (24 / 2) * 2 = 24 candles for this half of the cupcakes. Because Stephanie needs 12 candles for half of the cupcakes and 24 candles for the other half, she needs a total of 12 + 24 = 36 candles. Since Stephanie needs 36 candles to decorate all the cupcakes and she currently has 30 candles, Stephanie needs 36 - 30 = 6 additional candles.
So the answer is 6.

Question: Calvin has been saving his hair clippings after each haircut to make a wig for his dog. He has gotten 8 haircuts and knows that he needs 2 more to reach his goal. What percentage towards his goal is he?
Answer with step-by-step thinking: His goal is 10 haircuts because 8 + 2 = 10. He is 80% there because (8 / 10) x 100 = 80.
So the answer is 80.

Question: Jenna's doctor tells her that she should tan no more than 200 minutes a month. If she tans 30 minutes a day, two days a week for the first two weeks of the month, how many minutes can she tan in the last two weeks of the month?
Answer with step-by-step thinking:
First find how many minutes Jenna tans each of the first two weeks: 30 minutes / day * 2 days / week = 60 minutes / week. Then multiply that number by the number of weeks to find how many minutes Jenna tans in the first half of the month: 60 minutes / week * 2 weeks = 120 minutes. Then subtract that time from the total time Jenna can spend tanning to find how many more minutes she can tan: 200 minutes - 120 minutes = 80 minutes.
So the answer is 80.
