Answer this question:June has $500 for buying school supplies for the new school year. She buys four maths books at $20 each, six more science books than maths books at $10 each, and twice as many art books as maths books at $20 each. If she also bought music books, how much money did she spend on music books?
The total cost of maths books is 4 * 20 = $80$. She bought six more science books than maths books which totals 6 + 4 = 10 books. If each science book cost her $10 she spent 10 * 10 = $100 on science books. There were twice as many art books as maths books which total 2 * 4 = 8. The total cost for art books is 8 * 20 = $160. The total amount that she used for maths, science, and art books is 160 + 100 + 80 = $340. The amount she spent on music books is 500 - 340 = $160.
The answer is 160.

Answer this question:Henry believes in the famous phrase, "An apple a day, keeps the doctor away." If a box contains 14 apples, how many weeks can Henry and his brother spend eating 3 boxes of apples if they each eat 1 apple a day?
There are a total of 14 apples / box x 3 boxes = 42 apples in the 3 boxes. So, Henry and his brother each have 42 apples / 2 people = 21 apples / person to consume. Since there are 7 days in a week, thus, both of them can consume the 3 boxes of apples in 21 / 7 = 3 weeks.
The answer is 3.

Answer this question:Sam earns $10 an hour on Math tutoring. For the first month, he earned $200; and for the second month, he earned $150 more than the first month. How many hours did he spend on tutoring for two months?
For the second month, Sam earned $200 + $150 = $350. So, he earned a total of $200 + $350 = $550 for the first two months. Therefore, he spent $550 / $10 = 55 hours on math tutoring for the first two months.
The answer is 55.

Answer this question:Movie tickets cost $5 each on a Monday, twice as much on a Wednesday, and five times as much as Monday on a Saturday. If Glenn goes to the movie theater on Wednesday and Saturday, how much does he spend?
