The solution is (5, 15)
Multiply the second equation by 2 and then add through.
3x + 2y = 45
8x - 2y = 10
-----------------
11x = 55
x = 5
Then plug in to get the y value
3(5) + 2y = 45
15 + 2y = 45
2y = 30
y = 15
The population density of the city which is the ratio of population size and the land area is 1419 people per square mile.
- The initial population = 2496435
- The percentage increase in population = 7.9%
<u>The population of the city on 2015 can be calculated thus</u> :
- (1 + percent increase) × initial population
- (1 + 0.079) × 2496435 = 2693653.365 people
<u>The population of a city is calculated using the relation</u> :
- Population density = Population / Land Area
- Population density = 2693653.365/1898
- Population density = 1419.21
Therefore, the population density is 1419 people per square mile.
