a buffalo has a mass of 115 kg. the buffalo increase the mass per year by 85 kg. how many years will it take the buffaloes mass to increase to 3 tonnes?

Respuesta :

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
