Answer:

$\frac{1}{16}$ or in decimals: 0.0625

Step-by-step explanation:

4*4*4 is 4³ or 16*4 or 64

4*4*4*4*4 is $4^{5}$ or 16*16*4 or 256*4 or 1024

We have $\frac{64}{1024}$ which divided by 8 is $\frac{8}{128}$ which divided by 8 again is $\frac{1}{16}$

Orlov [11]

Answer:

8696.10

Step-by-step explanation:

If a car depreciates by 7% each year, this means that 7% of its value that year is subtracted from its previous value. In other words, you can multiply its value by (1-0.07)=0.93.

$12500\cdot 0.93^5\approx 8696.10$ . Hope this helps!
