The amount of bacteria in a Petri dish increases at a rate proportional to the amount present. At time t=0, the amount of bacteria in the dish is 10 grams. At time t=2, the amount of the bacteria in the dish is 30 grams. What is the amount of bacteria in the dish at time t=6?

A. 70 grams
B. 190 grams
C. 270 grams
D. 9270 grams

C. 270 grams

Step-by-step explanation:

-The growth of bacteria follows an exponential distribution expressed as:

Where:

Given the size at time t and time zero, we substitute in the function to calculate the rate of growth r:

#we use the calculated rate of growth to determine time at t=6:

Hence, the bacteria's size at t=6 is 270 grams
