[Question]Jill is the hairdresser for the school's dance team and has to braid 8 dancers' hair. If each dancer has five braids and each braid takes 30 seconds, how many minutes will it take to braid all the dancers' hair?
[Answer]First find the total number of braids among all the dancers: 8 dancers * 5 braids / dancer = 40 braids. Then multiply by that the time in seconds per braid to find the total time in seconds: 40 braids * 30 seconds / braid = 1200 seconds. Then divide the time in seconds by the number of seconds per minute to find the time in minutes: 1200 seconds / 60 seconds / minute = 20 minutes. The answer is 20.

[Question]If John travels 15 miles on a bike ride, and Jill travels 5 miles less, how many miles does Jim travel if he travels only 20% as far as Jill?
[Answer]To find how far Jim travels, we must first find out how far Jill did. To do this, we perform 15 - 5 = 10 miles in total for Jill. We then multiply 10 * .20 = 2 miles in total for Jim, since he only traveled 20% of the distance Jill did. The answer is 2.

[Question]John used to be able to squat 135 pounds. After training, he increased that by 265 pounds. He then gets a magical strength-increasing bracer that increases his strength by an additional 600%. How much can he now lift?
[Answer]He can lift 135 + 265 = 400 pound without the bracer. The bracer adds 400 * 6 = 2400 pounds. So he can now squat 2400 + 400 = 2800 pounds. The answer is 2800.

[Question]Ronald wants to make profits by re-selling some phones he bought a week ago. He bought 200 units for just $3000, and he wants to gain a third of the initial investment in profits when all units are sold. Including the profit margin, what will be the selling price for each phone?
[Answer]
The profit Ronald wants is $3000 / 3 = $1000. The profit per phone sold will be $1000 / 200 phones = $5 / phone. The cost of each phone is $3000 / 200 phones = $15 / phone. The selling price including the profit will be $15 / phone + $5 / phone = $20. The answer is 20.
