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

Answer:

B) 9

Step-by-step explanation:

110 + 75 + 11x - 9 + 8x + 13 = 360

19x + 189 = 360

19x (+ 189 - 189) = 360 - 189

19x = 171

19x/19 = 171/19

x = 9
