The purchase price of a new machine is 3500 000 dinars. its value will decrease by 300 000 dinars each year. write a linear model that expresses the value of the
machine (t) years after its purchased :

A) p = 300 000 -3500000t

B) p = 3500 000 +300000t

C) p = 3500 000-300000t

D) p = 300 000+3500000t
