Question 845977
Your initial equation is fine
(.50)(L)+ (.30)(16)=.35(16+L)
You messed up multiplying by 100
50L + 30*16 = 35*16 + 35L
50L + 480 = 560 + 35L
15L=80
L=80/15
L=5 1/3=5.33333

without multiplying by 100
(.50)(L)+ (.30)(16)=.35(16+L)
.50L+ 4.8=5.6+.35L
0.15 L=0.80
L=.80/.15 
L = 5.33333
