On January 1, 1985, Marc has the following two options for repaying a loan:

Aliun [14]

Answer:

The correct answer is

K = 29.0123 months

Step-by-step explanation:

The given variables are interest at 12 % monthly compounded

to find the number of months

Compound interest = $A=P(1+\frac{r}{n})^{nt}$ and

A = Future value.

P= Principal, initial value amount,

r= Interest rate

n= number of time units,

t = time

and $F = P(1+i)^{n}$ where

P = principal,

i = interest,

F = Future sum payment

n = number of payment time units

The two options have the same eventual value

Therefore we have

$100(1+\frac{r^{-60} }{n}) = 6000*((1+.01)^{-K})$

$100(\frac{1-1.01^{-60} }{.01}) = 6000*((1+.01)^{-K})$

Taking natural logarithm of both sides we have

K= -(㏑(10/6)+ $ln(1-1.01^{-60})$ )/㏑(1.01) = 29.0123 months

Alternatively we have

You have 2 different savings accounts. For Account A, the simple interest earned after 21 months is $13.65. For Account B, th

Rama09 [41]

Answer:

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P = principal

T = time in years

R = interest rate on the principal.

For account A, the simple interest earned after 21 months is $13.65. The interest rate is 3.9% for Account A

Let y represent the principal for account B. Therefore

P = x

I = $13.65

T = 21/12 = 1.75 years

R = 3.9

Therefore

13.65 = (x × 3.9 × 1.75)/100

1365 = 6.825x

x = 1365/6.825 = $200

For account B, the simple interest earned after 30 months is $40.25. The interest rate is 2.3% for Account B

Let x represent the principal for account A. Therefore

P = y

I = $40.25

T = 30/12 = 2.5 years

R = 2.3

Therefore

40.25 = (y × 2.3 × 2.5)/100

4025 = 5.75y

y = 4025/5.75 = $700

The principal for account A is $200

The principal for account B is $700

For account A, interest earned in the first month is

13.65/21 = $0.65

For account B, interest earned in the first month is

40.25/30= $1.34

Account B earned the most interest in the first month(the same interest is earned every month)
