oh hold on i should read first

anonymous · Answer

i think i do not understand what this is asking.  sorry.

anonymous · Answer

I got these two equations:
.45x + .10y = 10.35
x + y = 30

anonymous · Answer

I'm just not sure how to change 34.5% into a decimal .. I did it by just turning it into .345, which I think is correct, but I'm not sure. Sooo ... I want to see what other equations people got to see if I did it right.

anonymous · Answer

then 21 and 9 is your answer

anonymous · Answer

yes that is right.  34.5=.345

anonymous · Answer

Alright, thanks.

anonymous · Answer

and .345*30=10.35 so you have it.

anonymous · Answer

in which case my solution would have worked as well.
