3,850,000people
Step-by-step explanation:
Given
Total registered voters = 7million
If 55% of 10000 of the voters plans to vote for her, the number of people out of 10000 that plans to vote for her is expressed as:
55/100 × 10,000
= 55 × 100
= 5500
This shows that 5500 voters for every 10,000 plans to vote for her, if we have 7 million voters,
Hence x for every 7million plans to vote for her.
5500 = 10000
X = 7,000,000
Cross multiply
10,000x = 5,500 × 7,000,000
x = 5,500×700
x = 3,850,000
This shows that the population interest is 3,850,000people out of 7million
