A dependent variable represents the output of a function.
For example, someone needs to buy 20 pieces of fruit and decides to buy apples and bananas. If they select the number of apples first, the equation \(b=20-a\) shows the number of bananas they can buy. The number of bananas is the dependent variable because it depends on the number of apples.
