Comparing Store Layaway Plans

The video tutorial covers lesson 6.3c, focusing on comparing functions presented as graphs and descriptions. It explains how to write equations in slope-intercept form for both graphical and descriptive data, and how to compare them by converting to the same form. The lesson uses a practical example of comparing layaway plans for a pressure washer at two stores, analyzing the differences in down payments and weekly payments. The tutorial concludes with a comparison of the plans and a brief introduction to the next lesson on determining rate of change and initial value.

What is the first step in comparing functions presented as a graph and a description?

• Write an equation in slope-intercept form for the graph.

• Convert the graph to a table.

• Identify the input and output variables.

• Draw a graph of the description.

In Sam's scenario, what is the initial cost of the pressure washer?

• $200

• $250

• $150

• $100

What does the y-intercept represent in the context of Store A's graph?

• The total cost of the pressure washer.

• The initial down payment.

• The weekly payment amount.

• The balance owed after the down payment.

How is the slope of Store A's graph described?

• Positive 20

• Negative 20

• Positive 30

• Negative 30

What is the weekly payment amount for Store B?

• $20

• $30

• $100

• $50

How does the down payment for Store B compare to Store A?

• Both stores have the same down payment.

• Store A has a larger down payment.

• Store B has a smaller down payment.

• Store B has a larger down payment.

Which store's layaway plan takes longer to complete?

• Neither, they are paid upfront

• Store A

• Store B

• Both take the same time

What is the main advantage of comparing both stores' plans on the same graph?

• It displays the weekly payment amounts.

• It allows for easy comparison of payment duration.

• It highlights the differences in down payments.

• It shows the total cost of the washer.

What is the next topic after lesson 6.3c?

• Advanced graphing techniques

• Understanding decimals

• Determining rate of change and initial value

• Introduction to fractions

How many weeks does it take to pay off the layaway plan at Store B?

• 10 weeks

• 5 weeks

• 8 weeks

• 12 weeks
