PLEASE ANSWER How many liters of a 35% salt solution must be mixed with 20 liters of 70% salt solution to obtain a solution that
is 45% salt?
1 answer:
Answer:
50 liters
Step-by-step explanation:
Amount of salt in the 35% solution + amount of salt in the 70% solution = amount of salt in the 45% solution
0.35 x + 0.70 (20) = 0.45 (x + 20)
0.35 x + 14 = 0.45 x + 9
5 = 0.1 x
x = 50
