Let the amount of the first brand be x, and let the amount of the second brand be y.
0.09x + 0.14y = 240 * 0.13 .................(1)
x + y = 240 ..............(2)
y = 240 - x .......................(3)
Plugging the value for y from equation (3) into equation (1), we get:

...............(4)
Equation (4) simplifies to:
-0.05x = -2.4
giving the value for the required amount of 9% vinegar as 48 ml and the required amount of 14% vinegar as 240 - 48 = 192 ml.

Answer:
c= 12.19
Step-by-step explanation:
Let's solve for c.
5.3(4x−2.3)=21.2x+c
Step 1: Flip the equation.
c+21.2x=21.2x−12.19
Step 2: Add -21.2x to both sides.
c+21.2x+−21.2x=21.2x−12.19+−21.2x
c=−12.19
Answer:
c=−12.19
