Answer:
$9,583.33
Explanation:
The computation of the amount invested in the stock K is shown below
Let us assume the amount invested in stock K be Y
So according to this, following formula should be used
The Expected return of portfolio × Amount invested = Expected return of K × Amount invested in K + Expected return of L × Amount invested in L
0.101 × $ 15,000 = 0.088 × Y + 0.124 × ( $ 15,000 - Y )
$1,515 = 0.088Y + $ 1,860 - 0.124Y
0.036Y = $ 345
Y = $ 345 ÷ 0.036
= $9,583.33
