Q: Jeremy bought a computer for $3000, and some accessories for 10% of the price of the computer. How much money has Jeremy if, before the purchase, he had two times more money, than the cost of the computer itself?
A: At the start, Jeremy had two times more money than the price of the computer, which means he had 2 * 3000 = $6000. The cost of the accessories stands at 3000 * 1 / 10 = $300. This leaves Jeremy with 6000 - 3000 - 300 = $2700. The answer is 2700.
Question: The area of square A is 25. The area of square B is 81. What's the length difference between the sides of square A and B?
Answer: The area of a square is calculated as length * width. Because all a square has all sides equal then we can say that given a side S, the area is S * S. For square A of sides A, the area is A * A = 25 or A^2 = 25. Solving for A we know that A = 5. For square B of sides B, the area is B * B = 81 or B^2 = 81. Solving for B we know that B = 9. The side difference between A and B is 9 - 5 = 4. The answer is 4.

Question: Haley, Michael and Brandon were trying a marshmallow challenge to see who could hold more marshmallows in their mouths. Haley could hold 8 marshmallows in her mouth. Michael could hold 3 times as many marshmallows as Haley. Brandon could hold half as many as Michael. How many total marshmallows did all three kids hold in their mouths?
Answer: Haley held 8 marshmallows. Michael held 3 times Haley's, so he held 8 x 3 = 24 marshmallows. Brandon held half as many marshmallows as Michael, so he held 24 / 2 = 12 marshmallows. Together, they held 8 + 24 + 12 = 44 marshmallows. The answer is 44.
Q: Bob and Kate went to a restaurant for dinner. After they were done eating the waitress gave a $30 bill to Bob and a $25 bill to Kate, but told them they were eligible for special discounts; 5% for Bob, 2% for Kate. Considering the discounts, how much do they have to pay in total?
A:
5% of $30 is (5 / 100) * 30 = $1.5. The dollar amount of Bob's discount is $1.5 so he will pay $30 - $1.5 = $28.5. 2% of $25 is (2 / 100) * $25 = $0.5. The dollar amount of Kate's discount is $0.5 so she will pay $25 - $0.5 = $24.5. Altogether they will pay $28.5 + $24.5 = $53. The answer is 53.
