Question

Jane needs to make 10 liters of a solution that is 10% salt. She has a solution that is 5% salt and a solution that is 25% salt. How much of each solution should Mia use?
2.5 liters of the 5% salt solution and 7.5 liters of the 25% salt solution

8 liters of the 5% salt solution and 2 liters of the 25% salt solution

4 liters of the 5% salt solution and 6 liters of the 25% salt solution

7.5 liters of the 5% salt solution and 2.5 liters of the 25% salt solution

Answer 1

Answer:

2.5 liters of the 5% salt solution and 7.5 liters of the 25% salt solution

Step-by-step explanation:

0.05x + 0.25(10-x) = 0.10*10,

0.05x + 2.5 - 0.25x = 1,

-0.2x = -1.5,

x = 7.5,  liters of 5% salt solution

Answer 2

Answer:

2.5 liters of the 5% salt solution and 7.5 liters of the 25% salt solution

Step-by-step explanation:

0.05x + 0.25(10-x) = 0.10*10,

0.05x + 2.5 - 0.25x = 1,

-0.2x = -1.5,

x = 7.5,  liters of 5% salt solution
