Question 1065126
An amount is invested at 5%. Let this amount be x. Thus, 0.05x
The rest is invested at 4%: 22,000-x is the amount invested at 4%. Put it all together:
0.05x+0.04(22,000-x) = 940
0.05x+880-0.04x = 940
0.01x = 60 
x = 60/0.01 = 6,000 this is the amount invested at 5%
22,000-6,000 = 16,000 is the amount invested at 4%
-------------------------------------------------
Check:
6,000*0.05 = 300
16,000*0.04 =640
. . . . . .--------------
Total . . . 940 Correct
