PLEASE HELP 5. A bacteria has an initial population of 500 and is
doubling every hour.
Which equation could represent the situation
described and how long does it take for the
bacteria to reach 16,000?
a. 500(2)* = 16,000; After 16 hours
b. 2x + 500 = 16,000; After 7,750 hours
c. 500(2)* = 16,000; After 5 hours
d. 2x + 500 = 16,000; After 8,250 hours
