you deposited $2000 in an account. The account earns $120 simple interest in 18 months. What is the annual interest rate
Semenov [28]
Use the formula for simple interest:

i = p* r* t

Here, $120 = $2000*r* (18/12 years)

                   $120
Then  r = ------------------ = 0.04.  That's 4% per year.
                  $2000(1.5)

$1000 invested with compound interest at a rate of 15% per year for 9 years. Formula: M = P(1+ i)n Group of answer choices $3517
BaLLatris [955]

Answer:

Option A.

Step-by-step explanation:

Note: Let as consider, we have to find the total amount after 9 years.

It is given that,

Principal amount = $1000

Rate of compound (yearly) interest = 15% = 0.15

Time = 9 year

The formula for total amount is

M=P(1+i)^n

where, P is principal, i is rate of interest and n is number of years.

Substituting P=1000, i=0.15 and n=9, we get

M=1000(1+0.15)^9

M=1000(1.15)^9

M=1000(3.5178763)

M=3517.8763

M\approx 3517.88

So, the total amount after 9 years is $3517.88.

Therefore, the correct option is A.
