2) 3 : 15 = 1 : 5

3) 22 : 38 = 11 : 19

4) 2 : 5 = 26 : 65

Step-by-step explanation:

2) 5, 3, 1, 15

3 : 15 = 1 : 5

If you simplify 3 : 15 you get 1 : 5 and 1 : 5 = 1 : 5.

3) 19, 22, 11, 38

22 : 38 = 11 : 19

If you simplify 22 : 38 you get 11 : 19 and 11 : 19 = 11 : 19.

4) 65, 2, 26, 5

2 : 5 = 26 : 65

If you simplify 26 : 65 you get 2 : 5 and 2 : 5 = 2 : 5.

Nyla invested $200 in an account with a 0.75% annual interest rate.
She made no deposits or withdrawals on the account for 3 years. If
interest was compounded annually, what is the balance in her bank
account at the end of 3 years?
A=4.53

B=1,071.88

C=450.00

D= 204.53

Answers

Answer:

D

Step-by-step explanation:

.75% of 200 is 1.5

multiply that by 3

add the original amount

The $204.53 is the balance in her bank account at the end of 3 years option (D) 204.53 is correct.

It is given that the Nyla invested $200 in an account with a 0.75% annual interest rate.

It is required to find the balance in her bank account at the end of 3 years if compounded annually.

What is compound interest?

It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.

We can calculate the compound interest using the below formula:

[tex]\rm A= P(1+r)^t[/tex]

Where A = Final amount

          P = Principal amount

          r  = annual rate of interest

          t = How long the money is deposited or borrowed (in years)

We have P = $200

               r = 0.75% = 0.0075

               t = 3 years

Putting the values in the formula, we get;

[tex]\rm A= 200(1+0.0075)^3\\\\\rm A = 200(1.0226)\\\\\rm A = \$204.52[/tex]

or A ≈ $204.53

Thus, the $204.53 is the balance in her bank account at the end of 3 years option (D) 204.53 is correct.
