Therefore I earn $50 interest
Therefore I earn $30.88 interest.
I would do the first one.
Step-by-step explanation:
A.
Given , I invested $500 at 5% simple interest for 2 years.
P=$500, r =5% and t = 2 years
=$50
Therefore I earn $50 interest.
B.
Given , I invested $500 at 3% compounded monthly for 2 years.
P=$500, r =3% = 0.03 and t = 2 years
=$530.88
Interest = $(530.88-530) = $30.88
I would do the first one.
<u>Answer:</u>
The present value of 10,000 if interest is paid at a rate of 6.2% compounded weekly for 8 years is 6097.56
<u>Explanation:</u>
We know that compound interest is given by
Where ,
Where A = final amount (which is given to be = 10000)
P = Principal amount (which is the present amount which we have to find)
r = interest rate = 6.2 = 0.062
n = no. of times interest applied per time period = it is given that the interest is applied weekly, so in one year there are 52 weeks so n = 52
t = time period = 8 years
Substituting the given values, we get
P = 6097.5
We get, P = 6097.56 which is the present value of a sum of money
