Answer:
33.94 years
Step-by-step explanation:
m = 115
y = mx + b
Since the buffalo starts at 115 kg, the y intercept of the line would start at 115.
y = mx + 115
Each year the buffalo is increasing 85kg, so that is the slope.
y = 85x+115
You are looking for when the buffalo is equal to 3 tonnes, 3000kg.
3000kg = 85x +115
x = 33.94 years
