Answer:
109.6%
Step-by-step explanation:
Last year:
Company A stock + Company B stock = total amount of stock:
$3160 + $5800 = $8960
This year:
Company A stock: $3160 + ($3160*0.20) = $3792
Company B stock: $5800 + (5800*0.04) = $6032
Company A stock + Company B stock = total amount of stock:
$3792 + $6032 = $9824
Total amount of increase from last year:
(9824/8960)*100 = 109.6 percent
