Answer:
10.6
Step-by-step explanation:
The amount of salt in one liter is 1.2 ounces, meaning to make one pound (16 oz) it would take 13 1/3 liters of water.
For 2.5 pounds, it would be 2.5*16, or 40-- 40 liters for 2.5 pounds of salt.
40 liters in (U.S.) gallons is 40/ (approximately) 3.785 , or 10.5680, 10.6
The correct answer is 37.5.
0.35x + 0.60y = 0.40(x + y) where x = vol. of 35% and y = vol. of 60%
x + y = 20
solve this system of equations
x + y = 20
-0.05x +0.20y = 0
this gives x = 16 and y = 4
so you need 16 L of 35% and 4 L of 60% solution.

Step-by-step explanation: true
Pretty sure its D. because it is not a one to one ratio but it doesn't necessarily have to pass through the origin.
