Answer: 1 1/3 or 4/3
Step-by-step explanation: f(4) =1/3(4) = 4/3 = 1 1/3
The equation will be of the form:

where A is the amount after t hours, and r is the decay constant.
To find the value of r, we plug the given values into the equation, giving:

Rearranging and taking natural logs of both sides, we get:


The required model is:
I don't know the answer, but I suggest downloading the app: PhotoMath. It scans a math problem and shows you how to complete the problem. I hope this helped~!
I’m assuming you’re asking for the slope which is 3/4
