The rate of decay is the constant factor by which the quantity is being reduced over a given period. In this case, the rate of decay can be determined by the exponent in the equation.
The equation is y = 200(0.85)^4.
Here, the base of the exponent is 0.85, which means that each time period, the quantity is reduced by 0.85, or 85%.
Therefore, the rate of decay is 85%, which corresponds to option a.
