The exponential function that models the decay of the substance can be written as:
A(t) = A0 * (1 - r)^t
Where:
A(t) = amount of substance remaining after t years
A0 = initial amount of the substance (600 grams)
r = decay rate (6% or 0.06)
t = number of years
Plugging in the values:
A(t) = 600 * (1 - 0.06)^t
A(t) = 600 * 0.94^t
Therefore, the correct exponential function that models the decay of the substance is:
A(t) = 600 * 0.94^t
Option D: A(t) = 600 * 0.94^t
A(t) = A0 * (1 - r)^t
Where:
A(t) = amount of substance remaining after t years
A0 = initial amount of the substance (600 grams)
r = decay rate (6% or 0.06)
t = number of years
Plugging in the values:
A(t) = 600 * (1 - 0.06)^t
A(t) = 600 * 0.94^t
Therefore, the correct exponential function that models the decay of the substance is:
A(t) = 600 * 0.94^t
Option D: A(t) = 600 * 0.94^t
