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?
Answer: 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.

[Question]Kiki likes to spend her money on hats and scarves. When she buys twice as many hats as scarves, she spends 60% of her money on hats and the rest on scarves. If she currently has $90, how many scarves will she buy if they are sold at $2 each?
[Answer]Kiki spends 60 / 100 * $90 = $54 of her money on hats. The amount she spends on buying scarves is $90 - $54 = $36. If each scarf is sold at $2, Kiki will buy $36 / $2 = 18 scarves. The answer is 18.

Ryan used 36 / 3 = 12 tokens on Pac - Man. Ryan used 36 / 4 = 9 tokens on Candy Crush. Ryan used a total of 12 + 9 + 7 = 28 tokens on all three games. Ryan had 36 - 28 = 8 tokens left. Ryan’s parents bought him 2 * 7 = 14 more tokens. Ryan had 8 + 14 = 22 tokens after his parents bought him some. The answer is 22.
