  1. Use algebra to solve this. Let x be the number of whole-chicken dinners sold, and y be the number of half-chicken dinners.

    x + y = 400 (the number sold)
    12x + 6y = 4200 (gross receipts)
    12x + 12y = 4800
    6y = 600
    Two more steps and you will have the answer. You finish the problem.
