You can  put this solution on YOUR website! Let X = money that should be invested in money market 
    Y = money that should be invested in bonds 
    W = money that should be invested in international stock fund  
    Z = money that should be invested in domestic stock fund
 
Equations 
(1)  X + Y = 0.6(110,000) = 66,000 
     Y = 66,000 - X
 
(2)  Z = 4W
 
(3) Z + W = 0.4(110,000)
 
(4) .025X + .035Y + .04W + .06Z = 4,400
 
Substitute equation (2) in (3) 
4W + W = 44,000 
5W = 44,000 
W = 8,800 
Z = 4(8,800) = 35,200
 
Express equation (4) in terms of X 
.025x + .035(66,000-X) + .04(8,800) + .06(35,200) = 4,400
 
.025x + 2,310 - .035X = 4,400 - 352 - 2,112 
-.01x = 1,936 - 2,310 
X = -374/-.01 
X = 37,400 
Y = 66,000 - 37,400 = 28,600
 
Answer: 
Investment as follows 
$37,400 for money market 
$28,600 for bonds 
$8,800 for international stock fund 
$35,200 for domestic stock fund
