Agustin Fernandez · Answer 1

This number can be found using the Rule of 70, which describes the formula dt = 70 / r, where dt is the doubling time, and r is the annual rate of growth.

Step-by-step explanation:

24/6 = 4

20 x 2 = 40 x 2 = 80 x 2 = 160 x 2 = 320

20 - --> 320 in the first day.

Keep doing this equation. Multiply each day's end result by 2 four times for 9 more days.
