You can put this solution on YOUR website! 1. The average person expels 200 mL of water per day by sweating. This is 8% of the total output of water from the body. How much is the total output of water.
---------------
If 200 ml is 8%, the 25 ml is 1%. The total is 100%, 100*25.
Total = 2500 ml, or 2.5 liters
------------------
2. The population of Wyoming increased from 454,000 in 1990 to 494,000 in 2000. Find the percent of increase in population.
--------------
% = (494000 - 454000)/454000
= 40/454
= 0.0881
= 8.81%
------------
3. Find the amount owed if $3000 is borrow at 5%, compounded annually, for 2 years.
------------
For 2 years, assuming it's 5% per year, = $3000*1.05*1.05
= $3307.50
