Final answer:
To find the number of chickens after 3 years, you can use the formula: N = P(1 + r)^t, where N is the final number of chickens, P is the initial number of chickens (42), r is the rate of increase (0.25), and t is the number of years (3). Plugging in the values, we get N = 42(1 + 0.25)^3. Evaluating this, we get N = 42(1.953125). Therefore, after 3 years, you will have approximately 81.84 chickens on your farm.
Step-by-step explanation:
To find the number of chickens after 3 years, you can use the formula: N = P(1 + r)^t, where N is the final number of chickens, P is the initial number of chickens (42), r is the rate of increase (0.25), and t is the number of years (3).
Plugging in the values, we get N = 42(1 + 0.25)^3. Simplifying this equation, we have N = 42(1.25)^3. Evaluating this, we get N = 42(1.953125). Therefore, after 3 years, you will have approximately 81.84 chickens on your farm.
