Vinegar % in Dressing
percent ---------------- quantity
Dressing A 5.00% ---------------- x liters
Dressing B 15.00% ------ 370 - x mliters
Mixture 7.00% ---------------- 370
370
5.00% x + 15.00% ( 370 - x ) = 7.00% * 370
5 x + 15 ( 370 - x ) = 2590
5 x + 5550 - 15 x = 2590
5 x - 15 x = 2590 - -5550
-10 x = -2960
/ -10
x = 296 ml 5.00% Dressing A
74 ml 15.00% Dressing B
