Question

Mr. Allen needs 100 mL of a solution that is 30% vinegar, 15% lemon juice, and 55% water. How much of solution A will mr.Allen

Answer 1

Answer:

I got 0ml?

Step-by-step explanation:

Maybe I'm wrong, but by using this matrix equation:

0.1  0.2  0.4           x subone              30

.15  0.2  0.1     x     x subtwo         =    15  

.75 0.6 0.5            x subthree             55

and multiplying both sides by the inverse of the coefficient matrix (the first one), you get that he needs 0 ml of solution A

Answer 2

Answer:

30 mL

Step-by-step explanation:

Mr. Allen needs 100 mL of a solution that is

• 30% vinegar,
• 15% lemon juice,
• 55% water.

Thus, there are

$100\cdot 0.3=30\ mL$ of vinegar,

$100\cdot 0.15=15\ mL$ of lemon juice,

$100\cdot 0.55=55\ mL$ of water.
