**drwls**, Friday, February 19, 2010 at 2:27pmIf this is algebra, you should not have to make tables.

Let the mason's rate be x walls per hour and the apprentice's rate be 0.5 x walls per hour. Working together, their rate is 1.5x walls per hour.

1.5x * 12 h = 1 wall

x = 1/18 wall per hour

x/2 = 1/36 wall per hour

The apprentice alone would need 36 hours
