Answer:
$2960
Step-by-step explanation:
Lily has two times as much money invested in 8% stocks,
As she has in bonds paying 6%
Let the money invested in 8% stocks be 2x dollars,
The money in bonds paying 6% is then x dollars.
So, $2x() + $x(
) = $325.6
$0.16x + $0.06x = $325.6
$0.22x = $325.6
x = $1480
The money she has invested in stocks is 2x = 2 × $1480 = $2960
The marginal cost when x=8 is:
375
<h2>Step-by-step explanation:</h2>We know that the marginal function for a cost function C(x) at x=a
is given by:
C'(x) at x=a
Here we have the cost function C(x) as:
Now we find the derivative of C(x) with respect to x.
i.e.
( Since,
)
Hence, we get:
