Suppose that you purchase a machine for $800 at the beginning of the year and that the value of the machine on the retail market drops by $16 per month. Write a linear model for the current value P of the machine on the retail market (in dollars) at year
t (with t=0 being the year that the machine was purchased).

Note: the '' P(t)= '' is already provided and pay attention to units.

Answer :

Hi

T (0) = 800

T(n+1) = T (n) - 16

General formula is  :  T(n) = 800- 16*n  

with "n" the year you are.  

exemple :  if you search value of machine at year 3,  it's value is  :

t(3) =800 -16*3

t(3)= 800 -48

t(3) = 752
