To determine the number of voters who participated in the last election from both cities, we add the number of registered voters in Richardson and Plano to get 3780. Then, we calculate 3/4 of this total to find that 2835 people voted.
To find out how many people voted in the last election, we first need to calculate the total number of registered voters in both cities combined. We can do that by adding the number of voters in Richardson to the number in Plano:
1346 (Richardson) + 2434 (Plano) = 3780 (Total Voters)
Then, to find out how many of these voters actually voted, we need to calculate 3/4 of the total number of voters:
3/4 of 3780 = 2835
So, 2835 people voted in the last election from both cities combined.
