Question

If the pattern in the table continues, when will sales for pants equal sales for shirts?

Year 2003 2004 2005 2006
Shirts 4.5 6.0 7.5 9.0
Pants 3.8 5.3 6.8 8.3

Answer 1

It won't. Both are increasing by 1.5 every year. If you graph that, the lines will be parallel. Parallel lines have no intercept.
