A scientist is running an experiment with

two species of bacteria that grow exponentially.

If species A doubles in population every

two days, species B doubles in population

every five days, and each species began the

experiment with a population of 50 bacteria,

what will the difference be between the

populations of the two species after ten days?

(A) 200

(B) 800

(C) 1,200

(D) 1,400

    D 1,400

    Step-by-step explanation:

    Species A doubles every 2 days and species B doubles every 5 days, so in 10 days, species A will double 10/2 = 5 times and species B will double 10/5=2 times. After 10 days from an initial population of 50 in each species, species A will have 50 x 2 ^5 = 50 x 32 = 1,600 population while species B will have 50 x 2 ^2 = 200 population. Their difference is 1,600-200 = 1,400.
