Jose wants to make 6 qt. of a 54% saline solution by mixing together a 50% saline solution and a 60% saline solution. How much of each solution must he use? qt. of 50% solution, qt. of 60% solution

3.6 qt. and 2.4 qt respectively

Step-by-step explanation:

Let x be x% of 50% saline solution. And (100-x%) be the percentage of 60% saline solution.

54=x*(50/100)+(100-x)*(60/100), solving it we will get x=60%. So we need 3.6 qt. of 50% saline solution and 2.4 qt. of 60% saline solution

i would say the third one.

step-by-step explanation: liner would mean in a line and the only one that doesn't look like it's even thinking about forming a line would be the third one
