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
