stepladder [879]

Answer:

A = $45948

Step-by-step explanation:

Given the following data;

Principal = $8000

Interest rate = 6% = 6/100 = 0.06

Time = 30 years

To find the future value, we would use the compound interest formula;

$A = P(1 + \frac{r}{100})^{t}$

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

t is the number of years for the compound interest.

Substituting into the equation, we have;

$A = 8000(1 + \frac{6}{100})^{30}$

$A = 8000(1 + 0.06)^{30}$

$A = 8000(1.06)^{30}$

$A = 8000(5.7435)$

A = $45948

If k=100 - 4n what’s the value when n=60

dexar [7]

To solve this problem, start by plugging in your given n value.
This results in:
k = 100 - 4(60)

Next, simplify the parentheses by multiplying the -4 and the 60 together.
This leaves you with:
k = 100 - 240

To simplify for k, subtract 240 from 100 to get:
k = -140

So your final answer is k = -140 when n = 60
