A colony of bacteria is growing by 23% every other week. What is the equation that models this situation? Let A(t) be the number of bacteria after t weeks and b be the original number of bacteria?

Question options:

A(t)=b(0.77)t/2

A(t)=b(1.23)t/2

A(t)=b(1.023)t/2

A(t)=b(1.23)2t

A colony of bacteria is growing by 23% every other week. Let A(t) be the number of bacteria after t weeks and b be the original number of bacteria. How long will it take for the population to double? Order the steps that you would take to solve this problem.

Multiply both sides of the equation by 2.

Use the power rule for logs to bring t/2 out of the exponent.

Divide both sides by log(1.23)

Divide both sides of the equation by "b".

Take log of both sides.

Substitute A(t)/b=2
