Answer:
62 oz
Step-by-step explanation:
Let the volume of water to add be x so that the new volume will be (30+x) oz
The new concentration is now 15%, expressed in decimal as 0.15 and it is found by dividing the initial concentration by new volume
[tex]\frac {0.46*30}{30+x}=0.15\\\frac {0.46*30}{0.15}=30+x\\92=30+x\\x=62[/tex]
The volume of water to add is equal to 62 oz
