Answer:

$5151.42

Step-by-step explanation:

The formula you need is

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

where A(t) is the amount after the compounding, P is the initial investment, r is the interest rate in decimal form, n is the number of compoundings per year, and t is time in years.  The info we have is

A(t) = 8000

P = ?

r = .09

t = 5

Filling in we have

8000=P(1+\frac{.09}{2})^{(2)(5)}

Simplifying a bit and we have8000=P(1+.045)^{10}

Now we will add inside the parenthesis and raise 1.045 to the 10th power to get

8000 = P(1.552969422)

Divide away the 155... on both sides to solve for P.

P = $5151.42

15% = \frac{15}{100} =  \frac{30}{100} which gives you the whole quality of the number of 200

I took a photo cuz its long, its a math question​
Alex777 [14]

Answer:

The answer is 5 people.

Step-by-step explanation:

$9.50 times 5 people equals $47.50, plus the fee of $1.25, equals $48.75. With only $1.25 left over after that, you could not afford to pay for any more tickets for others to see the movie.

<em>Hope this helps!</em>
