Question: Claire was in charge of passing out free balloons to all the children at the fair. She started with 50 balloons. While passing 1 balloon to a little girl, 12 balloons floated away. Over the next thirty minutes, she gave 9 more away and grabbed the last 11 from her coworker. How many balloons does Claire have?
Answer: Step-by-step reasoning process: As she gave 1 balloon out, 12 balloons floated away plus she gave away 9 more balloons so she is down 1 + 12 + 9 = 22 balloons. She started with 50 and gave / lost 22 balloons so she has 50 - 22 = 28 balloons. She also took her coworkers last 11 balloons so her new total is 28 + 11 = 39 balloons.
So the answer is 39.

Question: Micheal decided to take some piano lessons. One lesson costs $30 and lasts for 1.5 hours. How much will Micheal need to pay for 18 hours of lessons?
Answer: Step-by-step reasoning process: One lesson lasts 1.5 hours, so 18 hours of them is 18 / 1.5 = 12 lessons. If one lesson costs $30, then 12 lessons cost 12 * 30 = $360.
So the answer is 360.

Question: Brenda volunteered to make 3 trays of banana pudding for the family reunion. Each tray of banana pudding would need 80 wafer cookies. A box of wafer cookies only had 60 cookies per box. Each box costs $3.50. How much will it cost her to buy just enough boxes for 3 trays of banana pudding?
Answer: Step-by-step reasoning process: Every tray needs 80 cookies and she's making 3 trays so 8 * 3 = 240. Every box of cookies has 60 cookies. She needs 240 cookies so 240 / 60 = 4 boxes. The boxes cost $3.50 each and she needs 4 boxes so 3.50 * 4 = $14.00.
So the answer is 14.

Question: Eliza can iron a blouse in 15 minutes and a dress in 20 minutes. If she spends 2 hours ironing blouses and 3 hours ironing dresses, how many pieces of clothes did she iron?
Answer:
Step-by-step reasoning process: Since 60 minutes equal 1 hour, in 2 hours, Eliza ironed blouses for 2 x 60 = 120 minutes. Eliza can iron 120 / 15 = 8 blouses. Since 60 minutes equal 1 hour, in 3 hours, Eliza ironed dresses for 3 x 60 = 180 minutes. Eliza can iron 180 / 20 = 9 dresses. In total, Eliza ironed 8 + 9 = 17 pieces of clothes.
So the answer is 17.
