Business Problems

Note: although the example in Table 8-2 calls for no compounding, you may specify the number of compounding periods used in calculations with the Nb Period item in the %Change sub-menu. Nb Period is the number of compounding periods used in calculations between the old value and new value. The default is 1, but to change the setting, key in a number with Nb Period displayed, followed by I.

After calculating the example above with no compounding, say, for example, you wish to calculate the percent change over six compounding periods:
