Answer provided by our tutors
STEP1 LET X BE AMOUNT INVESTED AT 11%
AND $5900 -X BE AMOUNT INVETSED AT 7%
STEP2 NOW WE GENRATE FOLLOWING LINEAR EQUATION
AS TOATL YEILDS IS $ 537
O.11 X + ( 5900 -X) 0.07 = 537
0.11X +413 - 0.07X =537
0.04X = 124
X=$ 3,100 AMOUNT INVESTED AT 11%
AND
5900 - 3100=$2800 AMOUNT INVETSED AT 7%
