Answer:
• Vinegar: 40 milliliters
• Italian dressing: 280 milliliters
Explanation:
Let the amount of vinegar to be used = x
Let the amount of Italian dressing to be used = y
The chef wants to make 320 milliliters of the mixture.
The chef plans to mix 100% vinegar with Italian dressing(12% vinegar) to make 320 milliliters of a mixture that contains 23% vinegar.
Thus, we have a system of linear equations.
Subtract (2) from (1):
Divide both sides by 0.88
Using equation (1), we solve for x:
Therefore, the chef should use 40 milliliters of Vinegar and 280 milliliters of Italian dressing.
