Answer:
We can solve this problem using the formula for exponential growth:
N = N0 * (1 + r)^t
where N is the final number of downloads, N0 is the initial number of downloads, r is the weekly growth rate as a decimal, and t is the number of weeks.
We know that N0 = 175, r = 0.165 (16.5% expressed as a decimal), and t = 12. Plugging these values into the formula, we get:
N = 175 * (1 + 0.165)^12
N ≈ 15,497
Therefore, the approximate number of times the app was downloaded after 12 weeks is 15,497.
