The initial number of bacteria in a Petri dish is 2,300 and grows at a rate of 3% per hour. Which best approximates the number of bacteria in the dish after 8 hours?

1803
2914
2,324
0

1. You don't need a calculator for this one. You KNOW it can't be 0 or 1803 since it MUST be more than 2300. And for 8 hours it is unreasonable to think it will grow only by 24 so the answer must be B; i.e., 2914.
