How do you solve (5.5+2.5)÷2×4 with pemdas

So its easy so () are first! 5.5 2.5 is 8. then 2x4 is 8 so 8/8 is 0 so thats your answer 0

PEMDAS is parenthesis, exponents, multiplication, division, addition, and subtraction. 
Knowing that, you do 5.5 plus 2.5 and you get 8 and then you do 8/2 = 4 times 4= 16.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
