<PRE><B>Question 1141485</B>
Ryan invested his savings in two investment funds.
a &amp; b
 The amount he invested in Fund A was 3 times as much as the amount he invested in Fund B.
a = 3b
 Fund A returned a 2% profit and Fund B returned a 3% profit.
 How much did he invest in Fund B, 
if the total profit from the two funds together was 630? 
.02a + .03b = 630
Replace a with 3b
.02(3b) + .03b = 630
.06b + .03b = 630
.09b = 630
b = 630/.09
b = $7000 in fund B
the
a = 3(7000)
a = $21000 in fund A
;
:
Check this, find the actual amt from each
.02(21000) = 420
.03(7000)  = 210
--------------------
totals amt: 630</PRE>
