## yomamabf 2 years ago The November 16, 2009 issue of the New York Times reported that there were 671,616 foreign students enrolled at US colleges and universities in 2008-09 — representing an 8% increase from the previous year. It was the largest percentage increase in more than 25 years.

How many foreign students were studying in US colleges and universities during 2007-2008?

2. sauravshakya

x+ 8% of x = 671,616

3. sauravshakya

Solve for x ... CAN U?

4. yomamabf

?

5. MathisAWESOMEWOO!!

6. yomamabf

... uh ok?

7. nubeer

suppose there was x students in 2007-2008 so 8% increase , 8/100 (x) 0.08x so x+0.08x = 671,616 can you find x?

8. yomamabf

i did but the answer came out totally different

9. nubeer

10. yomamabf

621,867 foreign students

11. yomamabf

but i got 617886.72

12. nubeer

hmm maybe solve again.. i am getting the right answer with the equation i wrote.

13. yomamabf

for which number

14. yomamabf

u got 621867?

15. nubeer

x+0.08x =671,616 1.08x=671,616 divide both sides by 1.08

16. yomamabf

wth..... i just got the answer but yyyy would u divide i dont get it

17. nubeer

bcos u have to find the x.. x is the number of students in 2007

18. nubeer

its 1.08x right now.. so to make x alone or isolate divide both sides by 1.08

19. yomamabf

ohhhh ok so its y=p(1+r)

20. nubeer

oh mm what is this lol?

21. yomamabf

thats the formula for the problem i used 671616=p(1+.08)

22. nubeer

ohh ok .. well i am not familiar with that formula.. but ya ok if that formula works fine then its ok

23. yomamabf

thank u

24. nubeer

you are welcome.
