Alice placed $1,900 in a savings account which earns 2.2% interest, compounded every year. How much will she have in the account
ella [17]

She will have $2118 in her account after five years

<h3>How to determine the amount in five years?</h3>

The given parameters about the compound interest are

Principal Amount, P = $1,900

Interest Rate, R = 2.2%

Time, t = 5

Compound interests are different from simple interest, and they are calculated using the following compound interest formula

CI = P(1 + R)^t - P

To calculate the amount, we have:

A = P + CI

So, the equation becomes

A = P + P(1 + R)^t - P

Evaluate the like terms

A = P(1 + R)^t

Substitute the known values in the above equation

A = 1900 * (1 + 2.2%)^5

Express 2.2% as decimal

A = 1900 * (1 + 0.022)^5

Evaluate the sum

A = 1900 * (1.022)^5

Evaluate the exponent

A = 1900 * 1.11495

Evaluate the product

A = 2118

Hence, she will have $2118 in her account after five years

5(n+4)/3=n-8<br> A.-24<br> B.24<br> C.22<br> D.-22<br> PLEASE HELP
arsen [322]

Start with

\dfrac{5(n+4)}{3} = n-8

Multiply both sides by 3:

5(n+4) = 3(n-8)

Expand both sides:

5n+20 = 3n-24

Subtract 3n from both sides:

2n+20 = -24

Subtract 20 from both sides:

2n = -44

Divide both sides by 2:

n = -22
