A poultry farmer has been keeping track of the number of chickens at his farm over previous years. Four years ago, the number of chickens was 64. The number increased by 50% each year for four years until the present day. In the future, the farmer considers the situation where the number of chickens increases at a constant rate equal to the rate of the most recent year or the situation where the number continues to increase by 50% per year. What is the difference in the number of chickens between these two situations two years from now?Choose 1 answer:(A) 0(B) 189(C) 405(D) 11
Q. A poultry farmer has been keeping track of the number of chickens at his farm over previous years. Four years ago, the number of chickens was 64. The number increased by 50% each year for four years until the present day. In the future, the farmer considers the situation where the number of chickens increases at a constant rate equal to the rate of the most recent year or the situation where the number continues to increase by 50% per year. What is the difference in the number of chickens between these two situations two years from now?Choose 1 answer:(A) 0(B) 189(C) 405(D) 11
Calculate Chickens After 4 Years: First, let's calculate the number of chickens at the end of the four-year period with a 50% increase each year.Initial number of chickens: 64Yearly increase: 50%We will use the formula for compound interest to calculate the number of chickens after four years, which is similar to calculating the future value of an investment.Number of chickens after n years = Initial number ×(1+rate)n
Calculate Chickens After 2 Years: Now, let's calculate the number of chickens after four years.Number of chickens after 4 years =64×(1+0.50)4=64×(1.50)4=64×5.0625=324 (rounded to the nearest whole number)
Constant Increase Calculation: Next, we need to calculate the number of chickens two years from now under the first scenario where the number of chickens increases at a constant rate equal to the rate of the most recent year.The rate of the most recent year is 50% of the number of chickens at the end of the fourth year.Constant increase = 50% of 324= 0.50×324= 162So, the number of chickens will increase by 162 each year for the next two years.
Calculate Chickens After 2 More Years: Now, let's calculate the number of chickens after two more years with the constant increase.Number of chickens after 2 more years (constant increase) = 324+162×2= 324+324= 648
50% Increase Calculation: For the second scenario, we need to calculate the number of chickens two years from now if the number continues to increase by 50 percent per year.Number of chickens after 1 more year (50% increase) = 324×(1+0.50)= 324×1.50= 486Number of chickens after 2 more years (50% increase) = 486×(1+0.50)= 486×1.50= 729
Calculate Difference: Finally, we calculate the difference in the number of chickens between the two scenarios two years from now.Difference = Number of chickens after 2 more years (50% increase) - Number of chickens after 2 more years (constant increase)Difference = 729−648Difference = 81
