Answer: D
Step-by-step explanation:
If we substitute -12 into this equation we get:
![-3[-12-8]+1.5](https://tex.z-dn.net/?f=-3%5B-12-8%5D%2B1.5)
![-3[-20]+1.5](https://tex.z-dn.net/?f=-3%5B-20%5D%2B1.5)
Because -20 is in absolute value, we simply just use 20.
Thus,

To solve for r means to isolate r.
A = p(1+rt)
A = p + prt
A - p = prt
(A - p)/pt = r
Done.
