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
