Percent of Democrats who could vote for Candidate A = 75% of 60% = 45%;
Percent of Republicans who could vote for Candidate A = 20% of 40% = 8%;

Percent of possible votes for Candidate A = 45% + 8% = 53%

The correct answer: B

Hope this helps!

Let’s assume there are 100 registered voters in the city. Thus, 60 voters are Democrats and 40 are Republicans.

We see that 0.75 x 60 = 45 Democrats and 0.20 x 40 = 8 Republicans are expected to vote for Candidate A. Thus, (45 + 8) / 100 = 53/100 = 53% of the registered voters are expected to vote for Candidate A.

Answer: B
