Question

Consider the population of the city of Beaumont. Over the course of a year, 800 people move into town. Of those that moved in, 180 have dark hair, 260 have red hair, and the remaining 360 are blonde. During this year a total of 1070 people move out, 470 with dark hair, 270 redheads, and 330 blondes. There are 223 newborns, 47 with dark hair, 90 with red hair, and 86 blondes. Finally, there are 168 deaths, 31 with dark hair, 66 with red hair, and 71 with blond hair. (Assume no one goes bald or changes their hair color.) What is the accumulation of red-haired people in Beaumont, for this year

Answer 1

There were 14 red-haired people accumulated in Beaumont, for this year.

Explanation:

• The number of people who moved into town is = 800

Number of dark haired people = 180

Number of red haired people = 260

Number of blonde haired people = 360

• The number of people who moved out of town is = 1070

Number of dark haired people = 470

Number of red haired people = 270

Number of blonde haired people = 330

• The number of newborns in town is = 800

Number of dark haired = 47

Number of red haired = 90

Number of blonde haired = 86

• The number of deaths in town is = 168

Number of dark haired people = 31

Number of red haired people = 66

Number of blonde haired people = 71

Compute the accumulation of red-haired people in Beaumont, for this year as follows:

Red hair = #Moved in - #Moved out + #Newborn - #Deaths

= 260 - 270 + 90 - 66

= 14

Thus, there were 14 red-haired people accumulated in Beaumont, for this year.
