Question: Matt can buy key chains in packs of 10 for $20 or in packs of 4 for $12. How much money can he save if he chooses to buy 20 key chains at a lower price?
Answer: The cost of each key chain in packs of 10 for $20 is $20 / 10 = $2. The cost of each key chain in packs of 4 for $12 is $12 / 4 = $3. There is a price difference of $3 - $2 = $1 per key chain between the two choices. By buying 20 key chains at a lower price, Matt can save 20x$1 = $20. The answer is 20.
[Question]Amaya is watching a movie that she finds kind of boring, so she keeps tuning out and having to rewind it to catch what she missed. She watches 35 minutes before she realizes she needs to rewind the movie to catch something she missed, a process that adds 5 minutes to her total viewing time. She watches the movie for another 45 minutes but has to rewind it again, adding 15 minutes to her total time. Finally, she watches the last 20 minutes uninterrupted. If she added up the duration of the film plus all the times she had to rewind and re-watch parts, how many minutes did it take her to watch the movie?
[Answer]Amaya watches the movie without rewinding for 20 minutes + 15 minutes + 45 minutes + 20 minutes = 100 minutes duration of the movie. However, Amaya also spent extra time re - watching parts she rewound, for 5 minutes + 15 minutes = 20 minutes. In all, Amaya spent 100 minutes + 20 minutes = 120 minutes watching the movie. The answer is 120.
Q: 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?
A: 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 is 570.
Question: Josh has $300 in his wallet, and $2000 invested in a business. If the business's stock price rises 30% and then he sells all of his stocks, how much money will he have in his wallet?
Answer: If the business's stock price rises 30%, then his share on the company is worth 30% multiplied by $2000 plus $2000 that he already had. That results in 30% * $2000 + $2000 = $600 + $2000 = $2600. Since he already had $300, with $2600 more he will have $300 + $2600 = $2900. The answer is 2900.
