1.
h=1.09L
36=1.09L
divide 1.09 into both sides. L=36/1.09=33in (inside leg measurement)
2.
x=amt invested in Leaders.
30000-x=amt invested in Templeton
.16x+.25(30000-x)=6060
.16x+7500-.25x=6060
-.09x+7500=6060
subtract 7500 from both sides. -.09x=-1440
divide -.09 into both sides. x=$16,000 invested in Leaders
30000-x=$14,000 invested in Templeton
Check:
16000*.16=2560
14000*.25=3500
==========>------
==========>6060 profit in 1 year
