If $75 is invested at an interest rate of 8% per year and is compounded monthly, how much money is in the account in 15 years?

Answers

The amount of money is $248.02.

Principal amount = P=75

Interest rate = r = 8% = 0.08

Number of years = t = 15

Number of times compounded in a year = n = 12

A = Amount after t years.

After 15 years there will be:

$A=P\left(1+(r)/(n)\right)^(nt)\nA=75\left(1+(0.08)/(12)\right)^(\left(12\cdot15\right))\nA=248.019110806\nA \approx 248.02$

Answer:

$248.03

Step-by-step explanation:

The formula you use for this is as follows:

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

where A(t) is the amount after the compounding is done, P is the initial amount invested, r is the interest rate in decimal form, n is the number of times the compounding is done per year, and t is the time in years. Using that information and filling in our equation gives us this:

$A(t)=75(1+(.08)/(12))^((12)(15))$

which simplifies down to

$A(t)=75(1+.0066667)^(180)$

which simplifies further to

$A(t)=75(3.307118585)$

which multiplies to $248.0338938. Round to the nearest cent to get your answer.

Write a system of equations to describe the situation below, solve using substitution, and fillin the blanks.Nora, an office manager, needs to find a courier to deliver a package. The first courier she isconsidering charges a fee of $14 plus $5 per kilogram. The second charges $15 plus $4 perkilogram. Nora determines that, given her package's weight, the two courier services areequivalent in terms of cost. What is the weight? How much will it cost?

Answers

The first courier service cost is;

$5x+14$

Where, x is the number of kilograms delivered;

The second courier service cost is;

$4x+15$

Equating it, we have;

$\begin{gathered} 5x+14=4x+15 \n x=1 \end{gathered}$

Thus, the weight that will result in equal cost is 1 kilogram.

And the cost is 5( 1 )+14 = $19
