Answer: 14.38%
Step-by-step explanation:
Worth of stock in Company A = $5990
Percent decrease = 20%
New worth = $5990 - (20% × $5990)
= $5990 - (0.2 × $5990)
= $5990 - $1198
= $4972
Worth of stock in Company B = $2450
Percent decrease = 8%
New worth = $2450 - (8% × $2450)
= $2450 - (0.08 × $2450)
= $2450 - $196
= $2254
Previous total worth = $5990 + $2450
= $8440
Total worth = $4972 + $2254
= $7226
The total percentage decrease in the investor's stock account will be:
= [($8440 - $7226) / $8440] × 100
=( $1214 / $8440) × 100
= 0.1438 × 100
= 14.38%
Answer:
16.5%
Step-by-step explanation:
Find new values:
5990(1−0.2)=4792
2450(1−0.08)=2254
Last Year This Year
Stock A 5990 4792
Stock B 2450 2254
Total 8440 7046
Find overall decrease:
8440(1−r)=7046
8440(1-r)/8440= 7046/8440
1−r=0.834834
SUBTRACT 1
−r=−0.165166
DIVIDE BY -1
r=0.165166
Multiply by 100 and round to nearest 10th
Final Answer: 16.5%
