Ouch! They were supposed to have

*given* you those formulas (

*and* explained them)!

The "annual" (or any other fixed time period) growth is supposed to use the compound-interest sort of formula:

. . . . ....where "A" is the ending amount, "P" is the beginning amount, "r" is the rate of growth (or decay) for a unit of time (usually "annual", so "yearly"), "n" is the number of compoundings per unit time (usually years), and "t" is the total amount of time (expressed in the same time units).

In your case, P = 886,362,000, r = 0.016, n = 1, and t = 2001 - 1992 = 9.

For "continuous" growth, you use the "continously compounded" form, given in terms of the natural exponential "e":

. . . . ....where "A", "P", "r", and "t" are defined as previously, and "e" is just

**the natural exponential**. You'd find your answer using the same values, but plugging them straight into your calculatur. (You'll probably be using a "second" function for the key labelled "LN".)
