40% of k liters of acid are added to 60% of w liters of water. Write an algebraic expression for the total volume of the solution.

Answer 1

Example to help you:
30% of 4L of orange juice is added to 70% of 5L of grapefruit juice, find the total volume.

Volume of orange juice = 30% of 4L
=0.30*4
=1.2L
Volume of grapefruit juice=70% of 5L
=0.7*5
=3.5L

Total volume = 1.2L+3.5L=4.7L

Answer 2

40% of k liters
0.40*kL
0.60*wL
0.40kL + 0.60wL = 1wL
is this the correct answer

Answer 3

Answer is good up to (0.4k+0.6w) L.
Since we do not know the values of k nor w, their coefficients cannot be added together.

The correct answer would be
(0.4k+0.6w) L.

Answer 4

(0.4k+0.6w)
