Answer:
- 15 mL of 100% vinegar
- 45 mL of Italian dressing
Step-by-step explanation:
Let v represent the amount of 100% vinegar to be included in the mixture. Then the amount of vinegar in the overall mixture is ...
1.00v + 0.08(60 -v) = 0.31(60)
0.92v = 60(0.23) . . . . . . . collect terms, subtract .08(60)
v = 60(0.23/0.92) = 15 . . . mL of vinegar
60 -v = 45 . . . mL of dressing
15 mL of vinegar and 45 mL of Italian dressing should be used.
