 "output": "Title: Quiz on Ratios, Proportional Relationships, Unit Rates, and Percent Changes\n\nInstructions: Read each question carefully and choose the best answer. For equations, you can either solve or recognize the relationship. For tables, identify the constant of proportionality.\n\n1. What is the ratio of apples to bananas in a basket?\n   A) 3 apples:4 bananas\n   B) 7 apples:5 bananas\n   C) 2 apples:3 bananas\n   D) 5 apples:4 bananas\n   E) 3 apples:2 bananas\n\n2. A store sells shirts for $20 each and pants for $30 each. What is the ratio of shirts to pants in cost?\n   A) 20:30\n   B) 10:20\n   C) 2:3\n   D) 1:2\n   E) 25:35\n\n3. A train travels 240 miles in 4 hours. What is the train's speed in miles per hour?\n   A) 240 miles / 4 hours = 60 mph\n   B) 240 miles / 40 hours = 6 mph\n   C) 120 miles / 3 hours = 40 mph\n   D) 240 miles / 360 hours = 0.667 mph\n   E) 240 miles / 48 hours = 5 mph\n\n4. A recipe calls for 3 cups of flour to make a cake. How many times more flour is needed for 6 cups of flour to make the cake?\n   A) Divide 6 cups by 3 cups = 2\n   B) Multiply 3 cups by 2 = 6 cups\n   C) Add 3 cups and 6 cups = 9 cups\n   D) Subtract 3 cups from 6 cups = 3 cups\n   E) Multiply 3 cups by 2 = 6 cups\n\n5. A store sells a toy for $18 and a similar toy for $24. What is the ratio of the cost of the more expensive toy to the cheaper toy?\n   A) 24:18 = 3:2\n   B) 24:18 = 4:3\n   C) 24:18 = 3:2\n   D) 24:18 = 4:3\n   E) 24:18 = 3:2\n\n6. A recipe calls for 4 cups of sugar to make a dessert. How many times more sugar is needed for 8 cups of sugar to make the dessert?\n   A) Divide 8 cups by 4 cups = 2\n   B) Multiply 4 cups by 2 = 8 cups\n   C) Add 4 cups and 8 cups = 12 cups\n   D) Subtract 4 cups from 8 cups = 4 cups\n   E) Multiply 4 cups by 2 = 8 cups\n\n7. A car travels 30 miles for every 5 gallons of gas. How many miles will the car travel for 8 gallons of gas?\n   A) Divide 8 gallons by 5 gallons = 1.6\n   B) Multiply 30 miles by 1.6 = 48 miles\n   C) Add 30 miles and 40 miles = 70 miles\n   D) Subtract 30 miles and 20 miles = 10 miles\n   E) Multiply 30 miles by 1.6 = 48 miles\n\n8. A store bought a book for $20 and sold it for $25. What is the profit?\n   A) Subtract $20 from $25 = $5\n   B) Multiply $20 by 1.5 = $30\n   C) Add $20 and $25 = $45\n   D) Divide $25 by $20 = 1.25\n   E) Multiply $20 by 1.25 = $25\n\n9. A recipe calls for 2 cups of sugar for every 5 cups of flour. If you use 8 cups of flour, how many cups of sugar are needed?\n   A) Divide 8 cups by 5 cups = 1.6\n   B) Multiply 2 cups by 1.6 = 3.2 cups\n   C) Add 2 cups and 8 cups = 10 cups\n   D) Subtract 2 cups and 5 cups = 3 cups\n   E) Multiply 2 cups by 1.6 = 3.2 cups\n\n10. A store bought an item for $10 and sold it for $15. What is the profit?\n   A) Subtract $10 from $15 = $5\n   B) Multiply $10 by 1.5 = $15\n   C) Add $10 and $15 = $25\n   D) Divide $15 by $10 = 1.5\n   E) Multiply $10 by 1.5 = $15\n\nAnswer Key:\n\n1.
