Question 55172: PLEASE HELP ME WITH THIS PROBLEM:
The population P of a certain culture is expected to be given by a model P=100e^rt where r is a constant to be determined and t is a number of days since the original population of 100 was established. Find the value of r if the population is expected to reach 200 in 3 days.

The population P of a certain culture is expected to be given by a model where r is a constant to be determined and t is a number of days since the original population of 100 was established. Find the value of r if the population is expected to reach 200 in 3 days.
P=200 and t=3


Take the natural log of both sides:
Use this rule to rewrite the equation:
Remember this rule




You need a scientific calculator for that.

Round off to wherever your asked.
Happy Calculating!!!
