If n=2h+1, where n is the number of water bottles and h is the hours, which is true about n and h?

In the equation n = 2h + 1, the relationship between n and h illustrates how one variable depends on the value of the other. Here, h is considered the independent variable because its value can be chosen freely without regard to n. As h changes, n is directly affected, meaning n relies on the value assigned to h.

For every value of h (the number of hours), there is a corresponding value of n, calculated by the equation. This clarifies that n is dependent on h—h can be varied, while n will respond accordingly based on the defined relationship. The structure of the equation clearly indicates that n derives from h, solidifying the notion of h as the independent variable and n as the dependent variable.
