Answer:
Correct answer: at 2 p.m. the population was 10,000
at 3 p.m. the population was 50,000
Step-by-step explanation:
At 1 p.m. population was 2,000
At 2 p.m. or after first hour, the population of bacteria increases
in this way 2,000 · k
At 3 p.m. or after second hour, the population of bacteria increases
2,000 · k²
At 4 p.m. or after third hour, the population of bacteria increases 2,000 · k³
2,000 · k³ = 250,000 => k³ = 250,000 / 2,000 = 125
k = ∛125 = 5 => k = 5
At 2 p.m. or after first hour, the population of bacteria was 2,000 · 5 = 10,000
At 3 p.m. or after second hour, the population of bacteria was 2,000 · 5² =
= 2,000 · 25 = 50,000
