Final answer:
The number of registered voters can be found by multiplying the percentage of registered voters by the total number of eligible voters.
Step-by-step explanation:
To find the number of people registered to vote, we can use the given information that only 62% of eligible voters were registered. The community has about 55,200 eligible voters. We can calculate the number of registered voters by multiplying the percentage of registered voters (0.62) by the total number of eligible voters (55,200).
Number of registered voters = 0.62 * 55,200 = 34,224
Therefore, the correct answer is a. 34,224.
