7. brittanyburton

9. andriod09

the equation is simple. it would be $population\div.03$

10. satellite73

hmmm

11. satellite73

actually i think i would be $53500\times (.97)^7$

12. brittanyburton

nope i lied i dont

13. satellite73

to decrease a number by 3% means you have $$97\%=.97$$ of it left to decrease by $$3\%$$ 7 times, multiply it by $$(.97)^7$$

14. andriod09

@satellite73 where'd you get the .97?

15. brittanyburton

okay @satellite73 is write

16. andriod09
