A biologist is researching a newly-discovered species of bacteria. At 8:00AM when she arrives at the lab, she puts a population of 600 bacteria into a favorable growth medium.

She measures the sample again before she goes home at 4:00PM and notes that the population is now 1300 bacteria.

When she comes back to the lab the next morning at 8:00AM, how many bacteria will there be?

Assume that the population of bacteria follows an exponential growth model.

Give your answer as a decimal number rounded to the nearest whole number.

Population = __________ bacteria
