Percentages: The most useful statistics ever invented

ANNUAL YIELD: TOTAL AVERAGE PERCENT INCREASE of an investment over a one-year period. Annual Yield and Annual Interest Rate are not always the same percentage. Example: Determine the annual yield if you began the year with $2400 and ended 1 year later with $2784. For example, you invest $1000 at an annual interest rate of 5%. ................
