The following data show the number of
Chinese citizens who immigrated to the U.S.
Use the data to predict how many Chinese
immigrated to the U.S. during the 1990.

1950s 10,000
1960s 35,000
1970s 124,000
1980s 389,000

• Math -

50s to 60s -- 25,000 increase
25,000/10,000 = 2.5 = 250%

60s to 70s -- 89,000 increase
89,000/35,000 = 2.5428 = 254%

I'm sure you can finish the problem the same way.

so than...

70's to 80's - 265000 increase
265000/124000=2.137= 213.7%

Right?

just wondering...

• Math -

Right.

How many Chinese do you think immigrated in the 90s?

• Math -

i'm guessing to Megan that it is 717.7%???

• Math -

Why would the percentage be two or three times greater than in the earlier decades?

Besides, you need to estimate the number of immigrants, not the percentage of increase.

• Math -

the percent i think is because in the early days the price wasn't that high or expensive as today.

my bad, heres my other, i think, ummm....

to start 10000
so if you add 10000 to 25000= 35000
then, 35000+89000=124000
nest, 124000+265000=389000
i'm guessing the total will be 540000???
