A growth medium is inoculated with 1,000 bacteria, which grow at a rate of 15% each day. What is the population of the culture 6 days after inoculation?

A 15% daily growth rate means the population is multiplied by 1.15 each day. After 6 days, the population is 1,000(1.15)^6, which is about 2,313 bacteria. Therefore, the correct choice is “y = 1,000(1.15)^6; 2,313 bacteria.”
