**Reiny**, Thursday, January 17, 2013 at 10:16amamount invested at 5% ---- x

amount invested at 2% ----- 1100 -x

.05x + .02(1100-x) = 49

.05x + 22 - .02x = 49

.03x = 27

x = 27/.03 = 900

**invested at 5% = 900**

invested at 2% = 200

check: 900+200=1100

.05(900) +.02(200) = 49

all is good!

**Dylan**, Thursday, January 17, 2013 at 10:16amx + y = 1,100

a + b = 49

(x+5%) + (y+2%) = 1,149

That's all I could take from the question. Now how you solve and get the answer is beyond me.

**Dylan**, Thursday, January 17, 2013 at 10:28amAhh makes much more sense when Reiny did it. I remember learning this in algebra. I have a tendency to give everything its own variable, which makes the problem impossible to solve i guess.
