Answer 1

66 which is letter C!

With proof and explanation:

Explanation:

Number of people who voted and worked on election day: 0.64

Multiply that with the number of people who voted: 0.64 x 50 = 32

Number of people who didn't vote but worked on election day: 0.4

Multiply that with the number of people who didn't vote: 0.4 x 85 = 34

Now add! 32 + 34 = 66!
