The value of the quantity after 99 months is 5228.58.
Given that, an initial value = 5900, rate of decay = 0.85% and time period = 7 years.
<h3>What is the exponential decay?</h3>
The quantity decreases slowly after which the rate of change and the rate of growth decreases over a period of time rapidly. This decrease in growth is calculated by using the exponential decay formula.
The exponential decay formula formula is
Here, the value
= 5900×
= 5900×0.8862
= 5228.58
Therefore, the value of the quantity after 99 months is 5228.58.
