Answer:
32
Step-by-step explanation:
2 x 2 x 2 x 2 x 2 = 32
Times 2 by 2, 5 times. I don't know if that makes since.

divide both sides by 3
x=4.3
Answer:
the difference of median before the well (which was 53 minutes) and after the well (which was 28 minutes) is 25 minutes
Step-by-step explanation:
A) Total = Principal * (1 + rate)^years
Total = 500 * (1.015)^years
b) The equation has to be solved for years.
http://www.1728.org/compint2.htm
Years = {log(total) -log(Principal)} ÷ log(1 + rate)
Years = [log (800) - log(500)] / log (1.015)
Years = (2.903089987 -2.6989700043) / 0.0064660422492
