Question

If country A has 164,050 million more computers than country B and the total number of computers for both countries is 319,750 million, find the number of computers for each country.

Answer 1

To find the number of computers for country A and country B, set up a system of equations and solve them simultaneously.

Step-by-step explanation:

To find the number of computers for country A and country B, we can set up a system of equations. Let's say the number of computers in country A is x million, and the number of computers in country B is y million. From the given information, we know that:

x = y + 164,050

x + y = 319,750

Solving these equations simultaneously, we can find the values of x and y. Substituting the value of x from the first equation into the second equation, we have:

(y + 164,050) + y = 319,750

2y + 164,050 = 319,750

2y = 319,750 - 164,050

2y = 155,700

y = 155,700 / 2

y = 77,850

Now, substituting the value of y back into the first equation, we can find the value of x:

x = 77,850 + 164,050

x = 241,900

Therefore, country A has 241,900 million computers and country B has 77,850 million computers.
