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

\frac {0.46*30}{30+x}=0.15\\\frac {0.46*30}{0.15}=30+x\\92=30+x\\x=62

The volume of water to add is equal to 62 oz

I wasn't in school today can someone explain how to do this
Pachacha [2.7K]
You have to multiply 7 3/4 to 9.

First, turn 7 3/4 to an improper fraction which is 31/4.
Next, you multiply 31/4 to 9/1(same thing as 9) across from each other.
Then, you get the answer 279/4(31 x 9 = 279 ;4 x 1 = 4; 279/4).
Last divide 279 to 4 and get 67.75( .75 = 3/4 ; 69 3/4).
