Snooker's lumber can convert logs into either lumber or plywood. In a given day, the mill turns out twice as many units of plywood as lumber. It makes a profit of $30 on a unit of lumber and $45 on a unit of plywood. How many of each unit must be produced and sold in order to make a profit of $12,240?

units of lumber = x
units of ply = 2x
30 x + 45 (2x) = 12240
120 x = 12240
