Answer:
a. 87,400 people
b. 87,400 people
c. 174,800 people
Explanation:
percentages are just estimates that add up to 100%.
US population: 874,000
Midwest: 10%
.10 x 874,000 = 87,400 people
South: 10%
.10 x 874,000 = 87,400 people
Midwest and Northeast combined: 10% + 10% = 20%
.10 x 874,000 = 87,400 people
87,400+87,400 = 174,800 people
