Q: Leon ordered 3 sets of toy organizers for $78 per set and 2 gaming chairs for $83 each. If there is a delivery fee that is 5% of the total sales, how much did Leon pay?
A: Three sets of toy organizers cost $78 x 3 = $234. Two gaming chairs cost $83 x 2 = $166. Leon's total orders amount to $234 + $166 = $400. Then, the delivery fee is $400 x 5 / 100 = $20. So, Leon had to pay a total of $400 + $20 = $420. The answer is 420.
Question: John makes 6 dozen cookies for a bake sale. He sells each cookie for $1.5 and each cookie costs $0.25 to make. He splits the profit between two charities evenly. How much does each charity get?
Answer: He makes 6 * 12 = 72 cookies. Each cookie makes a profit of $1.5 - $0.25 = $1.25. So he makes a profit of 72 * $1.25 = $90. That means each charity gets $90 / 2 = $45. The answer is 45.
[Question]After violating the group's policies, 20 members of a Facebook group were removed by the group's admin. If each member posted 50 messages per day in the group and the number of members in the group was 150 before the admin removed some, calculate the total number of messages the remaining members would send in a week.
[Answer]If there were 150 members in the group before the admin removed 20, then 150 - 20 = 130 members remained after 20 were removed. The group members each posted 50 messages in a day, a total of 50 * 130 = 6500 messages. In a week, with seven days, the group members would have posted 6500 * 7 = 45500 messages. The answer is 45500.
Q: Jamie's father gained 5 pounds over the holidays that he wants to lose so his pants will not be as snug. He asks Jamie to help him keep track of his calories. Jamie's father burns 2,500 calories of fat a day by doing light exercise. There are 3,500 calories in a pound of body fat. How many days will it take for Jamie's father to burn off 5 pounds if he does light exercise and sticks to eating 2000 calories a day?
A: First Jamie wants to figure out how many calories his father needs to lose from 5 pounds x 3500 calories each = 17,500 calories to burn off. Then Jamie needs to figure out how many calories his father will burn per day if he burns 2500 calories - eating 2000 calories = burning 500 calories a day. If Jamie's father wants to burn off 17,500 calories total at 500 calories a day, 17,500 / 500 = 35 days to burn off 5 pounds. The answer is 35.
Question: Two buses leave a pick-up point station with 60% and 70% of capacity full, respectively. If the people in the buses are all employees of a company, and the buses have a capacity of 150, calculate the total number of the employees in the two buses combined?
Answer: If the first bus is 60% full, it has 60 / 100 * 150 = 90 passengers. The second bus is 70% full, meaning it has 70 / 100 * 150 = 105 passengers. The total number of people in the two buses is 105 + 90 = 195. The answer is 195.
Q: The length of a rectangle is four times its width. If the area is 100 m2. what is the length of the rectangle?

Let L be the length and W be the width of the rectangle. Hence L = 4 * W. We now use the area to write 80 = L * W. Substitute L by 4 W in the equation above 80 = 4 * W × W = 4 W^2. Solve for W and find L. 4 W^2 = 100. W^2 = 25, W = 5 and. L = 4 * 5 = 20 m. The answer is 20.
