What base could be written in the blank to make the exponential function model 15% decay ? y= ^t\12

The base of the function should be b = 0.85

The form of the function should be

Where,

A should be the initial amount

b decrease rate (b <1)

t be time (years, months, days)

Now

So, the value of the base should be

= 0.85

So, the function should be
