Question 550176
<pre>

If interest is figured n=1 time a year (annually):

A = P(1 + {{{r/n}}})<sup>nt</sup>

A = P(1 + {{{.08/1}}})<sup>1t</sup

A = $8000(1 + .08)<sup>40</sup>

A = $8000(1.08)<sup>40</sup>

A = $173,796.17

if interest is figured 4 times a year (quarterly)

A = P(1 + {{{r/n}}})<sup>nt</sup>

If n = 1

A = P(1 + {{{.08/4}}})<sup>40*4</sup>

A = P(1 + .02)<sup>160</sup>

A = $190,159.26
