Help me please !!
( part A and B please )

Answer 1

A. y = 2000*
`0.9^(x\\)`

B. $1180.98

Explanation:

Exponential decay function follow the formula y = a
`b^(x)`, 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
