Question

At the local dairy farm, Kareem buys a 32-oz container of yogurt for $2.56. Jonah buys a 6-oz container of yogurt for $0.48. Are the cost, y, in dollars and the amount of yogurt, x, Proportional. Explain.

Answer 1

The cost in dollars and the amount of yogurt are proportional

Explanation:

Proportions

Two variables are proportional if the ratio or division between them is a constant value.

Kareem buys a 32-oz container of yogurt for $2.56. We can compute the ratio of the quantity of yogurt and price 32/2.56 and we get 12.5. Jonah buys a 6-oz container of yogurt for $0.48. The relation is now 6/0.48=12.5

Since both ratios are equal, we can say the amount of yogurt, and the cost in dollars are proportional variables
