The first bonus question of the pop quiz becomes easy once you know the formula: "Pert"
P = $21,817.10
e = 2.7...
r = 0.1673
t = 1
1. (21817.10) * exp (0.1673) = $25,790.19
The other bonus questions in this set I solve with ... [wait for it] ... SPREADSHEETS!
Of course, $25k is what you HAVE after 1 year, not what you MAKE. So, to answer the question, what you MAKE is:
$25,790.19 - $21,817.10 = $3,973.09
