You can put this solution on YOUR website! ----------------- percent ----------------quantity
Eye solution type I 10 ----------------x ml
Eye solution type II 1 ----------------15-x ml
Mixture 2.00% ---------------- 15
10x+(15-x)=2*15
10x+15-x=30
10x-x=30-15
9x=15
/9
x=1.67 ml 10.00% Eye solution type I
13.33 ml 1.00% Eye solution type II
