Hi there!

A dependent variable is one that is changed, when the independent variable changes.

For example, if we wanted to calculate how many dollars we've earned in a given amount of time, time would be the independant variable, because it is a constant and is not affected by how much many we earn. The amount of money we earned is directly affected by the independent variable, time.

Your answer is b.

Hope I helped!

Be sure to leave a "Brainliest" if I was helpful. Or not lol. I really don't care tbh XD
