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. Write an equation to represent this relationship.
A. Yes, because the ratios 2.560.48 and 632 are equivalent; y = 0.08x.
B. Yes, because the ratios 2.5632 and 0.486 are equivalent; y = 0.08x.
C. Yes, because the ratios 2.5632 and 0.486 are equivalent; y = 0.8x.
D. No, because the ratios 2.5632 and 0.486 are not equivalent; y = 0.08 + x.
