Houston Walsh · Answer 1

The answer is A).

Every year, you multiply the previous population by 3:

First year: 50,000 * 3

Second year: 50,000 * 3 * 3 = 50,000 * 3²

...

Fifth year: 50,000 * 3^5

For an indeterminate number of years, x, you have:

y = 50,000 * 3^x

50,000*3=150,000

150,000*5=750,000

(50000*3) 5
