Kaylee deposited $1,450 in an account that earns 2.596 interest compounded annually. Which function represents the situation, wh

e-lub [12.9K]

Answer:

$f(t) = 1450(1.025)^{t}$

Step-by-step explanation:

Given

$P =1450$ -- principal

$r = 2.5\%$ --- rate

$n = 1$ --- compounded once a year

Required

Determine the function for compound interest

Compound interest f(t) is calculated as:

$f(t) =P(1 + r/n)^{nt$

So, we have:

$f(t) = 1450(1 + 2.5\%/1)^{1 * t}$

$f(t) = 1450(1 + 2.5\%)^{t}$

$f(t) = 1450(1 + 0.025)^{t}$

$f(t) = 1450(1.025)^{t}$

After four years of college, Erica has to start paying off all her student loans. Her first payment is due at the end of this mo

tatiyna

Answer:

Therefore, the approximate monthly payment is $548.85

Step-by-step explanation:

The amount of student loans Erica currently has = $34,006.00

The duration over which Erica is to pay back the loan = 7 years

The annual interest rate for the loan = 9.1%

Therefore, we have the geometric sequence formula is given as follows;

$A_n = P( 1 + r)^n - M \times \left [ \dfrac{(1 + r)^n-1}{r} \right ]$

Where;

M = The monthly payment

P = The initial loan balance = $34,006.00

r = The annual interest rate = 9.1%

n = The number of monthly payment = 7 × 12 = 84

Aₙ = The amount remaining= 0 at the end of the given time for payment

Substituting the values into the above formula, , we get;

$0 = 34006 \times \left ( 1 + \dfrac{0.091}{12} \right )^{84} - M \times \left [ \dfrac{\left (1 + \dfrac{0.091}{12} \right )^{84}-1}{\dfrac{0.091}{12} } \right ]$

$M = \dfrac{34006 \times \left ( 1 + \dfrac{0.091}{12} \right )^{84} }{\left [ \dfrac{\left (1 + \dfrac{0.091}{12} \right )^{84}-1}{\dfrac{0.091}{12} } \right ]} \approx 548.85$

Therefore, the approximate monthly payment = $548.85
