Jason has decided to open a small rental business. He plans to rent lawnmowers (x1), snow blowers (x2), and garden tillers (x3). His objective is to maximize the profit he makes per machine. Constraint 1 represents his storage space requirement in square feet. Constraint 2 represents his labor maintenance time constraint (in minutes) per machine. Constraint 3 requires that he must have at least 15 lawnmowers while constraint 4 requires that he have no more than 10 snow blowers on hand. Constraint 5 requires that he have at least twice as many lawnmowers as garden tillers.

If the labor maintenance time falls to 1400 minutes, what will be Jason's profit?
