9. Jack bought a car for $17,500. The car loses $750 in value each year. Which equation represents the situation? options:
A. an = 18250n − 750
B. an = 750n + 18250
C. an = 18250n + 750
D. an = −750n + 18250

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !

its less than 713.21 but greater than 5.2
