Correct answer: A. The cost per minute, in dollars.

The given equation, C = 1 + 0.15m, is a linear equation that models the total cost of a scooter rental. In this equation, C is the total cost and m is the number of minutes. The equation is in the form y = b + kx (or y = mx + b), where b is the initial value (or y-intercept) and k is the rate of change (or slope). In this context, the initial value is the fixed, one-time cost, and the rate of change is the cost for each additional unit of time. The number 1 represents the initial fee of $1. The number 0.15 is the coefficient of m, which means it is the rate of change. For every minute (m) that passes, the total cost (C) increases by 0.15 dollars. Therefore, 0.15 represents the cost per minute of the rental. A is correct because 0.15 is the rate of change, representing the cost for each minute of the rental. B is incorrect. The initial fee is represented by the constant term, 1, not the coefficient of m. C is incorrect. The total number of minutes is represented by the variable m, not the number 0.15. D is incorrect. The total cost of the rental is represented by the variable C, not the number 0.15.
