Answer:

~9071

Explanation:

A culture started with 5,000 bacteria.

After 7 hours, it grew to 6,500 bacteria.

=> The number of bacteria that grew after 7 hours: 6500 - 5000 = 1500

=> The number of bacteria that will grow after 19 hours: 1500 x 19/7 = ~4071

=> The number of bacteria that will present after 19 hours:

N = 5000 + 4071 = ~9071

Hope this helps!
