Answer:
Investment in stock x = $7816.67 
Investment in stock y = $6183.33
Step-by-step explanation:
The computation of invest in Stock X and Stock Y is shown below:-
Let the weight be x 
x × 14% + (1 - x) ×8%
= 11.35% 
0.14x + 0.08 - 0.08x
= 0.1135 
0.14x - 0.08x
= 0.1135 - 0.08 
0.06x = 0.335 
x = 0.335 ÷ 0.06 
x = 55.83% 
Investment in stock x = x × Stock portfolio
= 55.83% × $14,000
= $7816.67 
Investment in stock y = 1 - 0.5583 × $14,000
= $6183.33
