Answer:
a) 
b) When t = 10, Q = 7.845.
Step-by-step explanation:
The value of a quantity after t years is given by the following formula:

In which
is the initial quantity and r is the rate that it changes. If it increases, r is positive. If it decreases, r is negative.
a) Write a formula for Q as a function of t.
The initial value of a quantity Q (at year t = 0) is 112.8.
This means that
.
The quantity is decreasing by 23.4% per year.
This means that 
So


b) What is the value of Q when t = 10?
This is Q(10).


When t = 10, Q = 7.845.
15 is the answer I think because that is the Greatest Common Factor of all three of them.
I hope this helps!
