Answer:

The country's population in 1950 is 1700000

Step-by-step explanation:

Given

Let the population in 2003 be q

Let the population in 1950 be p

[tex]q = 7800000[/tex]

Required

Determine the value of p

From the question, the equation becomes:

[tex]q = 1000000 + 4 * p[/tex]

[tex]q = 1000000 + 4p[/tex]

Substitute 7800000 for q

[tex]7800000 = 1000000 + 4p[/tex]

Collect Like Terms

[tex]7800000 - 1000000 = 4p[/tex]

[tex]6800000 = 4p[/tex]

Divide through by 4

[tex]p = 6800000/4[/tex]

[tex]p = 1700000[/tex]
