Kara and James both like to mix a little bit of milk with their eggs when they make scrambled eggs. The amounts they mix are in the following table.
Is there a proportional relationship between Kara and James' milk and egg amounts?
No, because there is not a constant of proportionality between Kara’s and James' recipes.
No, because both the number of eggs and the amount of milk is different for Kara and James.
Yes, because James used more milk since he used more eggs.
Yes, because the difference between their number of eggs is 1 and the difference between the amounts of milk is ½.
The cost of buying rice in bulk is proportional to the weight. Five pounds of rice costs $3.95. If C represents the total cost and p represents the weight in pounds, which equation could be used to show this relationship? What is the cost of 7 pounds of rice?
The equation C = 5p models the relationship. Seven pounds of rice costs $35.
The equation C = 0.79p models the relationship. Seven pounds of rice costs $5.53
The equation C = 3.95p models the relationship. Seven pounds of rice costs $27.65
The equation C = 1.27 p models the relationship. Seven pounds of rice costs $8.89
