I'm really not sure.
Sorry.
Answer:
what whats the question so I can answer
The answer would be B.
For these, you plug in 8 where there ia a variable. 2(8)-1=15
The answer would be .81 becuase you can't round the 1 up to 2 becuase the number in the thousandths place is not above 5.
Hope this helps!!
