The answer is C
Answer:
14%
Step-by-step explanation:
1. The formula to find percent change is
. Now, all we have to do is plug in the values to their corresponding variable.
2. (Solving)
- 14%
There we have an information of two functions 
Using this two functions
, we need to find the composition of functions (h\circ g)(t).
The composition of two functions h and g is the new function , by performing g first and then performing h.



Composition of h and g (t) = 

First plugin the value of 


We know that
, we need to find h(3t+3),
That is, to replace t by 3t+3,

Now distribute 2 into 3t+3,

Now plug in 


Thus the solution is (D).
