problem 1: restaurant revenue goes from $2,400 (month 1) to $3,600 (month 4). find the average rate of change per month.
Answer
Explanation:
Step1: Identify revenue and months
Initial revenue $y_1 = 2400$, final revenue $y_2=3600$, initial month $x_1 = 1$, final month $x_2 = 4$.
Step2: Use average - rate - of - change formula
The formula for average rate of change is $\frac{y_2 - y_1}{x_2 - x_1}$. Substitute the values: $\frac{3600 - 2400}{4 - 1}$.
Step3: Calculate the result
$\frac{3600 - 2400}{4 - 1}=\frac{1200}{3}=400$.
Answer:
$400$
