Jeanie likes mixing leftover salad dressings together to make new dressings. She combined 0.55L of a 90% vinegar salad dressing with 0.45 L of another dressing to make 1L of salad dressing that is 60% vinegar. What percent of the second salad dressing was vinegar?

Answer 1

Answer:

23$\frac{1}{3}$

Step-by-step explanation:

x % - the % of a 0,45 L salad dressing

0,55*0,9+0,45*(x/100)=1*0,6     |*10000

55*90+45x=6000

x=23$\frac{1}{3}$
