Simply make the substitution.
P = 3a + 4b -6c a=2, b=3, c=-1.
P = 3*(2) + 4*(3) - 6*(-1) Multiply out.
P = 6 +12 +6 = 24.
P = 24.

The probability is 0.2177.
The z-score associated with this income is
z = (525-490)/45 = 0.78
Using a z-table (http://www.z-table.com) we see that the area to the left of this score, less than the score, is 0.7823. We want the probability greater than this score, so we subtract from 1:
1 - 0.7823 = 0.2177.
