**Reiny**, Friday, March 15, 2013 at 1:56pmamount invested at 8% ---- x

amount invested at 12% --- y

x+y = 2500

.08x= 2(.12)y = .24y

times 100

8x = 24y

x = 3y

sub into the 1st

3y + y = 2500

4y = 2500

y = 625

then x = 1875

$1875 were invested at 8% and 625 were invested at 12%

check:

.08(1875) = 150

.12(625) = 75

we can see that 150 is twice 75
