Mathematics
1 answer:
Fudgin [204]3 years ago
6 0

Answer:

94%

Step-by-step explanation:

The whole thing is about averages. Currently the average an 87%, because 85+91+86 = 262. 262/3 = roughly 87%.

Now if she got another score, that would mean it would now be divided by 4 instead of 3. So the equation is:

(262+x)/4 = 89

           *4     *4

____________

262 + x = 356

-262         -262

____________

          x  = 94

3400 dollars is placed in an account with an annual interest rate of 8. 25%. How much will be in the account after 25 years, to
OLEGan [10]

The final amount in the account after 25 years is $24670.42.

<h3>How do you calculate the final Amount after 25 Years?</h3>

Given that 3400 dollars are placed in an account with an annual interest rate of 8.25% for 25 years.

The final amount in the account is calculated by the formula given below.

A = P ( 1 + \dfrac {R}{100})^T

Where A is the final amount, P is the initial principal balance, R is the interest rate, T is the time period.

The final amount is given below.

A = 3400 ( 1 + \dfrac {8.25}{100})^{25}

A = 3400 (7.256005874)

A = 24670.41997= 24570.42

Hence we can conclude that the final amount in the account after 25 years is $24670.42.
