Use the method of corners to solve the linear programming problem.

Soundex produces x Model A radios and y Model B radios. Model A requires 15 min of work on Assembly Line I and 10 min of work on Assembly Line II. Model B requires 10 min of work on Assembly Line I and 12 min of work on Assembly Line II. At most, 25 labor-hours of assembly time on Line I and 22 labor-hours of assembly time on Line II are available each day. It is anticipated that Soundex will realize a profit of $11 on model A and $9 on model B. How many satellite radios of each model should be produced each day in order to maximize Soundex's profit?

(x, y) =

What is the maximum profit (in dollars)?
