In 1960, the population of Colombia was about 16 million and the population of Argentina was about 20.6 million. Between 1960 and 2010, the population of Colombia increased by about 530,000 people per year, and the population of Argentina increased by about 340,000 people per year. Let P represent the population, in millions, and t represent the number of years since 1960. Which of the following system of equations can be used to find the year when both countries had approximately the same population?


A. P = 16 + 0.34t
P= 20.6 + 0.53t

B. P = 16 + 0.53t
P = 20.6 + 0.34t

C. P = 16 + 530,000t
P = 20.6 + 340,000t

D. P = 16t + 340,000
P= 20.6t+ 530,000

Answer:

B

Step-by-step explanation:

Columbia was at 16 million with an increase of 530 thousand which is 0.53 of a million so population or P = 16 + 0.53t when t = years

Argentina about the same thing but with different numbers

The system of the equations will be P = 0.53t + 16 and P = 0.34t + 20.6. Then the correct option is B.

What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

In 1960, the population of Colombia was about 16 million and the population of Argentina was about 20.6 million.

Between 1960 and 2010, the population of Colombia increased by about 530,000 people per year, and the population of Argentina increased by about 340,000 people per year.

530,000 people per year = 0.53 millions per year

340,000 people per year = 0.34 millions per year

Let P represent the population, in millions, and t represent the number of years since 1960.

Then the system of the equations will be

P = 0.53t + 16

P = 0.34t + 20.6

Then the correct option is B.
