Answer:
~9071
Step-by-step 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!
