Can someone help please this is urgent

$140.74

Step-by-step explanation:

Assuming this is a decaying exponential function, we can find a model for the depreciation in the form of v = a(b^t)

At t = 0, we get 5000 = a(b^0), which gives us a = 5000

At t = 1, we get 4000 = 5000b, such that b = 4/5

Now that our function is defined as v = 5000(4/5)^t, we can plug in t = 16 to solve for the value of the piano.

v = 5000(4/5)^16, which is approximately $140.74.  

es una operación aritmética.

no se que fórmula requiera, pero te puedo decir que es adición. deberías revisar porque tema vas y ver que fórmulas puedes aplicar.
