Advanced Math practice question

Answer: 900

Four hours contains two 2-hour periods, so the colony triples twice: 100 × 3 × 3 = 900.

Common wrong answers

If you answered 300

300 is after ONE tripling — that's at 2 hours, not 4.

If you answered 1200

1,200 is 100 × 3 × 4, treating the tripling as happening once per hour times... it triples once every 2 hours: two triplings, 100 × 9.

If you answered 8100

8,100 is 100 × 3⁴, tripling every hour instead of every 2 hours.
