Here goes -

The percent W of municipal solid waste recovered is shown in the bar graph. The linear model is W=.737x + 25.7, where x = 0 represents 1995, x=1 represents 1996 and so on.

Based on this model, when did the percent of waste recovered first exceed 26%?

In what years was it between 26% and 28%?

Well looking at the table anybody can reach the answer, but I can not lay it out in a formula that makes sense.

I was trying to do 26.4> .737x + 25.7

which comes to .949 > x, what would you do with that?

How should this problem be setup?

The bar graph looks like this

year percent

1995 26.0

1996 26.4

1997 27.2

1998 27.4

1999 28.1

2000 30.1
