Final answer:
The equation that represents the proportional relationship between the number of oranges, x, Brooke squeezes and the amount of juice in ounces, y, she makes is y = 2x.
Step-by-step explanation:
The equation that represents the proportional relationship between the number of oranges, x, Brooke squeezes and the amount of juice in ounces, y, she makes is d. y = 2x.
In a proportional relationship, the two variables are directly proportional, meaning that a change in one variable will result in a proportional change in the other variable. In this case, if Brooke squeezes twice as many oranges, she will make twice as much juice. Therefore, the equation y = 2x represents this relationship.
