Question

a phone company charges for service according to the formula: $c(n)=19 + 0.04n$, where $n$ is the number of minutes talked, and $c(n)$ is the monthly charge, in dollars. the rate of change in this equation is: the initial value in this equation is: question help: video submit question

Explanation:

Step1: Identify the form of the equation

The equation $C(n)=19 + 0.04n$ is in the slope - intercept form $y=mx + b$, where $m$ is the rate of change and $b$ is the initial value.

Step2: Determine the rate of change

In the equation $C(n)=19 + 0.04n$, the coefficient of $n$ is the rate of change. So the rate of change $m = 0.04$.

Step3: Determine the initial value

In the equation $C(n)=19 + 0.04n$, the constant term is the initial value. So the initial value $b = 19$.

Answer:

The rate of change in this equation is: $0.04$
The initial value in this equation is: $19$
