Understanding Ratios and Graphs

The video tutorial covers the concept of ratios and their application in real-life scenarios. It begins with a baker's use of flour for muffin batches, explaining how to calculate the required flour for multiple batches. The tutorial then demonstrates graphing these ratios. It proceeds to analyze Drew's car washing charges, showing how to determine costs for different numbers of cars. Finally, it examines McKenna's earnings from shoveling snow, illustrating how to maintain a consistent earning ratio. Each example emphasizes the importance of understanding and applying ratios in various contexts.

If a baker uses 8 cups of flour for one batch, how many cups are needed for 4 batches?

• 24 cups

• 32 cups

• 40 cups

• 16 cups

What is the constant ratio of flour to batches in the baker's example?

• 1 to 6

• 1 to 8

• 1 to 9

• 1 to 7

What is the relationship between the number of batches and cups of flour on the graph?

• It forms a straight line

• It forms a circle

• It forms a zigzag

• It forms a curve

Drew charges a fixed rate for washing cars. If he charges $15 for 2 cars, how much does he charge for 6 cars?

• $60

• $75

• $45

• $30

How much does Drew charge for 4 cars if he charges $15 for 2 cars?

• $35

• $20

• $25

• $30

If the ratio of cars washed to dollars earned is 2 to 15, what is the charge for 10 cars?

• $65

• $60

• $70

• $75

McKenna earns $18 for shoveling snow 3 times. How much does she earn for shoveling 6 times?

• $36

• $24

• $30

• $42

What is the ratio of times McKenna shovels snow to her earnings?

• 1 to 5

• 1 to 6

• 1 to 7

• 1 to 8

If McKenna shovels snow twice, how much does she earn?

• $10

• $12

• $14

• $16

What is the pattern observed in the graph of McKenna's earnings?

• It forms a straight line

• It forms a curve

• It forms a zigzag

• It forms a circle
