Solving a system of equations we can see that:
First, let's define the variables:
With the given information we can write 3 equations:
A = (3/4)*V
V = K - $18
A + V + K = $386.4
Then we need to solve a system of equations:
A = (3/4)*V
V = K - $18
A + V + K = $386.4
We can first replace the first equation into the third to get:
(3/4)*V + V + K = $386.4
And rewrite the second to get:
k = V + $18
And replace that in the other equation:
(3/4)*V + V + V + $18 = $386.4
Now we can solve this for V:
V*(1 + 1 + 3/4) = $386.4 - $18
V*(11/4) = $368.40
V = (4/11)*$368.40 = $133.96
Now that we know the value of V, we can replace it in:
K = V + $18 = $133.96 + $18 = $151.96
A = (3/4)*V = (3/4)*$133.96 = $100.47
