The sum eighty two dollars to spend on seven books after buying them she had twelve dollars how much did each book cost

So first of all write down 82 / 12 and do the problem.Divide 82 / 12.

Next you get the answer which is,based on a calculator,which is 6.83333333333.

But because it's money well I'm guessing it could be 6.83 or 6.833 or the real answer.

The question is confusing but I hope I could help :D

Y=-2x-6 is the answer
