Mary will inflate a total of 10 balloons / minute x 30 minutes = 300 balloons. Jess will inflate a total of 7 balloons / minute x 30 minutes = 210 balloons. Christina will inflate a total of 4 balloons / minute x 15 minutes = 60 balloons. Combining all balloons, they made 300 balloons + 210 balloons + 60 balloons = 570 balloons.
The answer: 570
Reverse engineering the question: Mary, Jess, and Christina want to decorate a party room with balloons. Each person inflates balloons at different speeds, and they only have 30 minutes to inflate as many balloons as possible. Mary inflates 10 balloons per minute, Jess inflates 7 balloons per minute and Christina came 15 minutes late and was the slowest one inflating 4 balloons per minute. How many balloons can they inflate before running out of time?
Reasoning and answer: First calculate the weight - based charge by multiplying the package's weight in pounds by the price per pound: 5 pounds * $0.80 / pound = $4.00. Then add the weight - based charge to the flat fee to find the total cost: $4.00 + $5.00 = $9.00.
The answer: 9

Kyle and his mom eat a total of 2 + 1 = 3 cookies. Kyle and his mom eat a total of 2 + 2 = 4 brownies. The number of cookies remaining is 60 - 3 = 57 cookies. The number of brownies remaining is 32 - 4 = 28 brownies. From selling his cookies, Kyle makes 57 * $1 = $57. From selling his brownies, Kyle makes 28 * $1.50 = $42. Kyle would make a total of $57 + $42 = $99 if he sold all of his baked goods.
The answer: 99
Reverse engineering the question: Kyle bakes 60 cookies and 32 brownies. Kyle eats 2 cookies and 2 brownies. Kyle's mom eats 1 cookie and 2 brownies. If Kyle sells a cookie for $1 and a brownie for $1.50, how much money will Kyle make if he sells all of his baked goods?
Reasoning and answer: Antonia buys 5 different supplements where 3 bottles have 120 pills per bottle, so she has 120 pills x 3 bottles = 360 pills. 2 of the bottles Antonia buys have 30 pills each x 2 bottles = 60 pills. She has purchased 360 pills + 60 pills = 420 pills total in the 5 bottles. Antonia has filled her 7 - day pill box for 2 weeks, so 7 days x 2 weeks = 14 days. On each of the 14 days she fills it with 5 pills, so after 14 days she has used 14 x 5 = 70 pills. Since Antonia had 420 total pills in all 5 bottles and then she fills her pillbox with 70 pills, she has 420 - 70 = 350 pills. Antonia will have 350 pills left after 2 weeks.
The answer: 350

Reasoning and answer: First find how many pearls Jamie collects per dive by multiplying the number of oysters by the chance each oyster has a pearl: .25 pearls / oyster * 16 oysters / dive = 4 pearls / dive. Then divide the number of pearls he wants by the number of pearls per dive to find the number of dives: 56 pearls / 4 pearls / dive = 14 pearls / dive.
The answer: 14
What was the question?
Question:
25% of oysters have pearls in them. Jamie can collect 16 oysters during each dive. How many dives does he have to make to collect 56 pearls?
