+510 Enter your answer, rounded to the nearest whole number, in the box.
+9468 population after 0 hours = 50
population after 18 hours = 2 * 50
population after 2*18 hours = 2 * 2 * 50
population after 3*18 hours = 2 * 2 * 2 * 50 = 2^3 * 50
population after x*18 hours = 2^x * 50
x*18 = h
x = h/18
population after h hours = 2^(h/18) * 50
population after 60 hours = 2^(60/18) * 50 ≈ 504
