Answer:
R = 40t + 20
Step-by-step explanation:
We need to use the equation y = mx + b to solve this because it's linear.
"m" is the slope, or the rate. Here, we know that the population increases by 40 rabbits per month, which means m = 40.
"b" usually means that fixed, initial amount. Here, we know that the population begins at 20 rabbits, which means b = 20.
Plug these in:
R = mt + b
R = 40t + 20
