Q: Dan spent an hour doing 400 work tasks at $0.25 each. Then Dan spent an hour doing 5 work tasks at $2.00 each. How much more did Dan make doing the good work compared to the lower-paid work?
A: Dan spent an hour doing 400 tasks * $.25 = $100. Dan spent an hour doing 5 tasks * $2.00 each = $10.00. Dan made $100 - $10 = $90.00 per hour more doing the higher paid work. The answer is 90.
Question: There are 360 balls in the ball pit. If a quarter of the balls in the ball pit are red and a fifth of the remaining balls are blue. How many of the balls are neither red nor blue?
Answer: A quarter of the balls are red and therefore there are 360 x (1 / 4) = 90 red balls. When you remove the red balls from the ball pit there are 360 - 90 = 270 remaining balls. A fifth of the remaining balls are blue, and therefore there are 270 x (1 / 5) = 54 blue balls. The total of red and blue balls equals 90 + 54 = 144 balls. When you remove the red and blue balls from the total there are 360 - 144 = 216 balls that are neither red nor blue. The answer is 216.
[Question]In a studio audience of 100 people, 40% of these people have an envelope taped underneath their chairs. 20% of these people will have "You Won" in their envelope, the rest will have empty envelopes. How many people will win a prize?
[Answer]40% of the 100 studio audience will have an envelope under their chair so .40 * 100 = 40 people will find an envelope. 20% of these 40 people will find a "You Won" notice so only .20 * 40 = 8 people will win. The answer is 8.
Q: 40 less than 10 times Diaz's age is 20 more than 10 times Sierra's age. If Sierra is currently 30 years old, how old will Diaz be 20 years from now?
A: If Sierra is currently 30 years old, 10 times her age is 30 * 10 = 300. Twenty more than 10 times Sierra's age is 300 + 20 = 320. 320 is 40 less than ten times Diaz's age so 10 times Diaz's age is 320 + 40 = 360. If ten times Diaz's age is 360, Diaz is 360 / 10 = 36 years old. Twenty years from now, Diaz will be 20 + 36 = 56 years old. The answer is 56.
Question: James dumps his whole collection of 500 Legos on the floor and starts building a castle out of them. He uses half the pieces before finishing and is told to put the rest away. He puts all of the leftover pieces back in the box they came from, except for 5 missing pieces that he can't find. How many Legos are in the box at the end?
Answer: James starts with 500 Legos and uses half of them, leaving 500 / 2 = 250 Legos unused. He puts those unused Legos away but since he's missing 5 he only puts 250 - 5 = 245 Legos away. The answer is 245.
