[Question]The price of two kilograms of sugar and five kilograms of salt is $5.50. If a kilogram of sugar costs $1.50, then how much is the price of three kilograms of sugar and a kilogram of salt?
[Answer]Two kilograms of sugar is priced at $1.50 x 2 = $3. Three kilograms of sugar is priced at $1.50 x 3 = $4.50. So five kilograms of salt is priced at $5.50 - $3 = $2.50. Thus, a kilogram of salt is priced at $2.50 / 5 = $0.50. Hence, three kilograms of sugar and a kilogram of salt.s price is $4.50 + $0.50 = $5. The answer is 5.
Q: In Mr. Bolton's class of 25 students, 2/5 of the students like maths, 1/3 of the remaining students like science, and the rest of the students like history. Calculate the combined total number of students who like history and those who like maths.
A: If there are 25 students in the class, then 2 / 5 * 25 = 10 students like maths. The number of students who don't like math is 25 - 10 = 15 students. If 1 / 3 of the students that don't like math like science, then 1 / 3 * 15 = 5 students like science. The remaining number of students who enjoy history is 15 - 5 = 10. The combined total for the students who want history and maths is 10 + 10 = 20. The answer is 20.

[Question]The school decided to add 20% to the gym budget. In a normal month, they could buy 15 dodgeballs for $5 each if they spent the entire budget on that. If they only buy softballs instead, which cost $9 each, how many can they buy with the new budget?
[Answer]The old budget was $75 because 15 x 5 = 75. They are adding $15 to the budget because 75 x .2 = 15. The new budget is $90 because 75 + 15 = 90. They can buy 10 softballs on the new budget because 90 / 9 = 10. The answer is 10.
Q: A factory decides to stop making cars and start making motorcycles instead. When it made cars, per month, it cost $100 for materials, they could make 4 cars, and they sold each car for $50. Now that they make motorcycles it costs $250 for materials, but they sell 8 of them for $50 each. How much more profit do they make per month selling motorcycles instead of cars?
A: They sold $200 worth of cars each month because 4 x 50 = 200. They made $100 a month off cars because 200 - 100 = 100. They sold $400 worth of motorcycles each month because 8 x 50 = 400. They make $150 a month off motorcycles because 400 - 250 = 150. They make $50 more a month off motorcycles than cars because 150 - 100 = 50. The answer is 50.
