Answer:

A) Exponential decay, 55% decrease

Step-by-step explanation:

The b is less than 1, so that means it's decaying. Since b = 0.45 and that the formula for an exponential decay is a(1- percent in decimal form)^x, all you have to do is find out what the decimal was BEFORE you subtracted it from 1.

So: 1 - x = 0.45

x = 0.55

0.55 = 55%
