( part A and B please )

Answer:
A. y = 2000*[tex]0.9^{x\\}[/tex]
B. $1180.98
Step-by-step explanation:
Exponential decay function follow the formula y = a[tex]b^{x}[/tex], with a being the initial value and v being 1 - the rate of decrease.
a = 2000
b = 1 - .1 = 0.9
In order to find the value in 2017, we plug 5 in for x, as it is 5 years later, and get a value of 1180.98
