Karl was attempting to calculate economic figures. He found the following equation to be true:
fp - w = 10000
If f = 5 and w = 125i, what is p?
f * p - 125 i = 10000
5 p - 125 i = 10000 well obviously p must have = 25i in it for the 125 i to disappear
then for the real part 5 (p) = 10 000
real part p = 2000
p = 2000 + 25i
