It would be two places to the right of 0 because -3+5=2
He used 40 pounds of the candy worth $1.25 and 30 pounds of the candy worth $1.6.
For the answer to the question above, If you've noticed, the statement mentioned "a number". Let's assign x to be the number. The first statement is twice a number (2x). Then, decreased by the quotient of that number and 2 (-x/2). Lastly, the statement at least 12 is written as >12.
So the answer is
2x - (x/2) >12
