If there were nine people still there after the one person left, then there were 10 people to start. If the amount each one of them was going to pay is x, then the amount they now each have to pay is (in dollars) x+.60. The total bill didn't change; so
10x+=+9%28x%2B.60%29

That should be an easy equation to solve.

Note that you need to remember that the solution to the equation is the amount each person would have paid if there had still been 10 people there. That's not the answer to the problem; the answer is the amount of the total bill.
