Being that I have two known factors and one one unknown factor, I have pretty confident that this can be solved by an algebraic equation. 10x + x - 2 = 175, but I'm not sure If I even have the right equation. Below is the question that I'm trying to solve.

A company dining together find that the bill amounts to $175. However, two were not allowed to pay. The rest found that their shares amounted to $10 per person more than if all had paid. How many were in the company?
