A group of mice is called a "mischief". A mischief of field mice currently has a population of 45 mice. There is plenty of food and only a few predators nearby, so the population doubles every month. Which equation can be used to find t, the number of months until the population reaches 360 mice?

Question

a) 45(2)^t = 360
b) 45 (3)^t = 360
c) 45t^2 = 360
d) 90t = 360
e) 45(2)^t + 45 = 360
f) 45 +2t = 360

Answer 1

a) 45(2)^t = 360
