To determine how many of the 1,000 additional voters would prefer Candidate 3 or 4, we need to know the percentages or proportions that currently favor each candidate based on previous survey data.
Let's assume you have the following data based on the previous survey of voters:
- Candidate 1: 40%
- Candidate 2: 30%
- Candidate 3: 20%
- Candidate 4: 10%
Now, to find out how many of the 1,000 additional voters would likely prefer Candidate 3 or 4, we can combine the percentages of both candidates:
\[ \text{Total preference for Candidate 3 and 4} = \text{Percentage for Candidate 3} + \text{Percentage for Candidate 4} \] \[ = 20% + 10% = 30% \]
Next, we calculate how many of the 1,000 voters that corresponds to:
\[ \text{Number of voters preferring Candidates 3 or 4} = 30% \text{ of } 1,000 \] \[ = 0.30 \times 1000 = 300 \]
Thus, if 1,000 more voters are surveyed, about 300 of them will likely prefer either Candidate 3 or Candidate 4.
In conclusion, based on the given assumptions and calculations, the answer is 300 voters will likely prefer Candidate 3 or 4. If you have different percentages or information, you can substitute those values into the calculations following the same method.
