Question

From 1965 to 2000, twice as many people immigrated to the United States from the Philippines as from Vietnam. The total number of immigrants from these two countries was 2,100,000. How many people came to the United States from each country?

Answer 1

Data:

• Twice as many people immigrated from the Philippines as from Vietnam.

,

• People immigrated from Vietnam ( ,V ,)

,

• People immigrated from Philipines (, P ,)

Procedure:

0. We have to build two equations based on the information provided:

`P=2V`
`V+P=2,100,000`

2. Replacing the first equation in the second, we get the following equation:

`V+2V=2,100,000`
`3V=2,100,000`
`V=(2,100,000)/(3)`
`V=700,000`

3. Then, we replace this value in the first equation:

`P=2V`
`P=2\cdot700,000`
`P=1,400,000`

Answer:

• People immigrated from Vietnam = 700,000

,

• People immigrated from Philipines = 1,400,000
