The formula for compound growth is: Where,

P is the future value is the initial despositr is the yearly price of interestn is the number of times compounding happens ( n = 1 once annual compounding, n = 2 when semi-yearly compounding, n = 4 as soon as quarterly compounding etc.)t is time in years

A.

You are watching: Suppose you deposit 2000 in a savings account

Here we desire to understand P, offered , r is 0.04, n is 1 (considering that annual compounding) and also t is 3. dollars

B.

Everypoint is exact same in this problem as component A, simply t is not 3, t is 18. Similarly, we solve: dollars

C.

Here we desire to number out t, provided P=2500, , r is 0.04, n is 1 (considering that annual compounding). We have: To fix this exponential component, we take Natural Logarithm (ln) and usage our properties of logarithms and fix for t.
