A bird sanctuary has 23 parakeets and is planning a breeding program to increase the number of birds. The program aims to increase the number of parakeets by 18% each year. The number of parakeets, N, can be found using the formula N = c(1.18)^t, where c is the initial number of parakeets and t is the number of years. How many parakeets will there be after 9 years? A 405 B 102 C 244 D 27 Solution The formula for N, the number of parakeets is N = c( 1.18)t where c is the initial number of parakeets and t is the number of years. Here, c = 23 and t = 9. Therefore, N = 23(1.18)9 = 23*4.435453859 = 102 ( on rounding off to the nearest whole number.The answer B is correct..
