Answer:
12.5%
Step-by-step explanation:
80 - 70 = 10
10 / 80 = 0.125
Convert decimal to percent.
0.125 = 12.5%
Answer:
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1 + r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = $300
r = 10% = 10/100 = 0.1
n = 2 because it was compounded 2 times in a year(6 months).
t = 3 years
Therefore,
A = 300(1 + 0.1/2)^2 × 3
A = 300(1 + 0.05)^6
A = 300(1.05)^6
A = $402.03
dropped $3 means "-3", increased $6 means "+6"
the price dropped twice so 2(-3) and increased once by 6
so, 2(-3) + 6 = 0
the change in price is $0
