Vocabulary

Callie earns money by dog sitting. Based on the table, is the relationship between the amount Callie earns and the number of days a proportional relationship? Step 1:

Step 2: How can you use the constant rate to find how much Callie earns for 10 days of dog sitting?

The table shows the distance Allison drove on one day of her vacation. Is the relationship between the distance and the time proportional? Did she drive at a constant speed? Explain.

Two pounds of cashews cost $19.00 and 8 pounds cost $ Show that the relationship between the number of cashews and the cost is proportional. Then write an equation for the relationship. Describe the proportional relationship in words.

How can you use your equation to find the cost of 6 pounds of cashews?
