There are 4 choices for Mayor (including choosing nobody), 5 choices for councilwoman, and 4 choices for DA, so:
But you have to subtract the one disallowed possibility that is counted above, namely not voting for anyone at all.
Final tally: 79.

A citizen can vote for mayor in 4 ways..( any one of 3 candidates or no one )
similarly, for city councilwoman .........5 ways.
for district attorney........... 4 ways.
total ways = 4*5*4 = 80
but, here there is one way when he didn't vote for any position..
so, subtract 1 from total 80.
total no. of ways =79
