Answer:
The population size is 55.9597 (≅ 56)
Step-by-step explanation:
Since the population of protozoa develops at a constant growth rate of 0.4416 per member per day.
Then;
Day 0 = 3
Day 1 = 3 + (3 x 0.4416) = 4.3248
Day 2 = 4.3248 + (4.3248 x 0.4416) = 6.2346
Day 3 = 6.2346 + (6.2346 x 0.4416) = 8.9878
Day 4 = 8.9878 + (8.9878 x 0.4416) = 12.9568
Day 5 = 12.9568 + (12.9568 x 0.4416) = 18.6785
Day 6 = 18.6785 + (18.6785 x 0.4416) = 26.9269
Day 7 = 26.9269 + (26.9269 x 0.4416) = 38.8178
Day 8 = 38.8178 + (38.8178 x 0.4416) = 55.9597
After eight days, the population size would be 55.9597 (≅ 56).
