How many ml of terpin hydrate elixirs containing 33mg/5ml and 5mg/5ml needed to prepare 6 fl oz of an elixir containing 4mg terpin hydrate per ml?

My calculation: 33mg/5ml = x/100ml - 660mg changes 0.66gm

5mg/5ml = x/100ml - 100mg - 0.1gm

4mg/1ml = x/100ml - 400mg - 0.4gm

1oz = 30 ml

1oz/30ml = 6oz /x , x = 180ml

0.66 0.3

0.4

0.1 0.26

total 0.3 + 0.26 = 0.56

0.3/0.56 = x/180ml x= 96ml 33mg/5ml answer

0.26/0.56 = x/180ml x= 83 5mg/5ml answer
