A property company sold 20% more houses in 2007 than in 2006. If the company sold 426 houses in 2007, calculate how many houses it sold in 2006. Show every step.

If you don't know basic mathematics you should not seek the profession of accounting.

Logic says that if the sales are 20% greater then the sales in 2006 were 426 * 0.80

Sounds like a grade school math homework assignment to me.

Yeah me too but just maybe someone is confused by the logic

Yes, percentages can be confusing. For example, If I sell 50 one year and 100 the next, I have a 100% increase. However, If I sell 100 one year and 50 the next, I have a 50% reduction. So what is it!
