2. AriPotta

that'll give ye the number of white balls

3. heyheuhru

|dw:1353115049676:dw|

4. AriPotta

no :/

5. heyheuhru

204.8?

6. heyheuhru

or 205 bleh

7. AriPotta

|dw:1353115107314:dw| so he's adding 70 white balls

8. heyheuhru

what about the 12 ugh this sucks where did the 80 come from?

9. AriPotta

what 12? :/

10. heyheuhru

1280 i mean

11. AriPotta

|dw:1353115263887:dw|

12. heyheuhru

ohhh

13. AriPotta

128(10) = 1280 16(x) = 16x

14. AriPotta

1280/16 = 80

15. AriPotta

so 80 - 10 = 70. he's adding 70 white balls

16. AriPotta

is this making sense?

17. heyheuhru

why are you subtracting 10 again?

18. AriPotta

because x is the total number of white balls AFTER adding. and 10 is the number of white balls already in there. we have to subtract the original from the new

19. AriPotta

to see what was added

20. heyheuhru

I get it now, thank you :)

21. AriPotta

can you find out how many striped ball were added now?

22. AriPotta

23. heyheuhru

hmmm 43?

24. heyheuhru

wait wait 42!

25. heyheuhru

what would the ratio be then? :/

26. AriPotta

yup :) good job. and thanks for the testimonial :3

27. AriPotta
