The correct answer is 120
Let the price = P , the years = x , depreciation rate = d<span> and original cost = W
</span>∴
![P = W * (1-d)^x](https://tex.z-dn.net/?f=P%20%3D%20W%20%2A%20%281-d%29%5Ex)
when W = 25,000 , d = %8 = 0.08 and x =7
∴
P = 13,946.165 ≈ 13,946 to the nearest dollar
The price <span>after 7 years = $13,946</span>
Answer:
Correct choice is B
Step-by-step explanation:
Unknown leg x in right triangle is opposite to the angle of the measure of 50°. Use the definition of the sine of the angle:
![\sin \alpha=\dfrac{\text{opposite leg}}{\text{hypotenuse}}.](https://tex.z-dn.net/?f=%5Csin%20%5Calpha%3D%5Cdfrac%7B%5Ctext%7Bopposite%20leg%7D%7D%7B%5Ctext%7Bhypotenuse%7D%7D.)
Hence,
![\sin 50^{\circ}=\dfrac{x}{12}\Rightarrow 0.766=\dfrac{x}{12}.](https://tex.z-dn.net/?f=%5Csin%2050%5E%7B%5Ccirc%7D%3D%5Cdfrac%7Bx%7D%7B12%7D%5CRightarrow%200.766%3D%5Cdfrac%7Bx%7D%7B12%7D.)
