The exponential equation that represents how many grams of the compound will remain after 8 hours is:
B: C=260(0.962)^8
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
A radioactive compound with mass of 260 grams decays at a rate of 3.8% per hour, hence the equation for the mass after t hours is given by:


After 8 hours, the amount is given by:

Hence option B is correct.

I’ll recommend b or c so choose answer c
Answer:
it would be 69 because you would round .5 to 1 then 1 plus the 68 from the 68.52 making it 69
