Problem 7: Diffusion. Crossing a membrane by simple diffusion can be distinguished from facilitated diffusion because: If the particles can move through the lipid bilayer by simple diffusion, then there is no limit to the number that can fit through the membrane.
The second way to calculate compound interest is to use a fixed formula. The compound interest formula is ((P*(1+i)^n) - P), where P is the principal, i is the annual interest rate, and n is the number of periods. Using the same information above, enter Principal value into cell A1 and 1000 into cell B1.
Compound Interest Basics. Imagine $10,000 in an account that yields 8 percent per year and compounds once per year. At the end of the first year, you'd have $10,800. If the account didn't compound, you'd get another $800 at the end of the second year for a total of $11,600.
