Help please. .....................
viva [34]

we can use formula

y=ab^x

now, we can find a and b

Initially , price is 500

so,

At x=0,y=500

500=ab^0

a=500

now, we can plug back

y=500(b)^x

At x=3,y=10

we can use it and find b

10=500(b)^3

now, we can solve for b

and we get

b=0.27144

so,

annual depreciation rate is 27.144%.......Answer
