Hi there
The formula of the future value of annuity ordinary is
Fv=pmt [(1+r)^(t)-1)÷r]
Fv future value?
PMT 500
R 0.06
T 8 years
Fv=500×(((1+0.06)^(8)−1)÷(0.06))
Fv=4,948.73
Option c

Answer:
72°
Step-by-step explanation:
The lengths 25 cm and 8 cm are the sides of the rectangle.
See the attached diagram of rectangle ABCD.
Now, let us assume the diagonal AC makes x° angle with the shorter side BC i.e.∠ BCA = x°
So, using trigonometry we can write
⇒ 
degrees ≈ 72 degrees {Rounded to nearest degree} (Answer)
To find the number of CD on sale, we can set an equation.
Let y be the number if CD.
As she bought 40%, the amount she bought= 40%y
The equation:
40%y = 80
0.4y = 80
y = 80÷0.4
y=320
Therefore there were originally 320 CDs.
