At the local bakery, Sarah buys a 12-oz loaf of bread for $3.00. Ben buys a 5-oz loaf of bread for $1.25. Are the cost, y, in dollars and the amount of bread, x, in ounces proportional? Write an equation to represent this relationship.

• Yes, because the ratios 12/3.00 and 5/1.25 are equal; The equation is y=4x.

• Yes, because the ratios 3.00/12 and 5/1.25 are equal; The equation is y=0.25x.

• No, because the cost per ounce is different for Sarah and Ben.

• Yes, because the ratios 3.00/12 and 1.25/5 are equal; The equation is y=0.25x.
