the y is going up by 180
Answer:
$4088.5
Step-by-step explanation:
Given data
Price a = $6500
Rate of depreciation r= 14.3%
Time x= 3 years
The exponential function Decay is described as
y= ab^x
For decay
b= 1-r
a.
Hence the exponential function that model the value of the computer is
y=a(1-r)^x
b.
y= 6500(1-0.143)^3
y= 6500*(0.857)^3
y= 6500*0.629
y=$4088.5
Hence the value of the computer after 3 years is $4088.5
