Answer: The required percentage would be 5.4%.
Step-by-step explanation:
Since we have given that
Worth of Company A = $4150
Worth of Company B = $6820
So, increase in Company A = 6%
increase in Company B = 5%
According to question, it becomes,

So, the total percentage increase in the investor's stock account would be

Hence, the required percentage would be 5.4%.
180=(9X-11)+(4X+1)+(7X-3)
180=20x-13
193=20x
9.65=x

Given:
<span>Face value $4,530,
discount rate 7.2%,
time 125 days
Discount on Simple Discount note:
Discount = Maturity Value * discount rate * term
Discount = 4,530 * 0.072 * 125/360
Discount = 113.25
Proceeds for the simple discount note
Proceeds = Maturity Value - Discount
Proceeds = 4,530 - 113.25
Proceeds = 4,416.75
The proceeds for the simple discount note is $4,416.75</span>
