Answer:
"If you don't live in Florida, then you don't live in Miami"
Explanation:
Currently taking discrete math... this one hits close to home haha.
The starting statement is an implication in the form:

p: if you live in Miami
q: then you live in Florida
The contrapositive of this implication will be in the form:

: if you don't live in Florida
: you don't live in Miami
Combine the two with the implication for the final phrase:
"If you don't live in Florida, then you don't live in Miami"
