Answer:
B. The circumference of a balloon is a function of the amount of air you pump into the balloon.
Explanation:
When the amount of air pumped into a balloon increases, the circumference also increases.
Thus, we can say that the circumference of the balloon is dependent on the amount of air pumped in.
Thus, we have two variables:
• Dependent Variable,: Circumference
,
• Independent Variable,: Amount of air
This means that the circumference of a balloon is a function of the amount of air you pump into the balloon.
Option B is correct.
