    We know that total production , A+B+C =500 units.
    We know that B=2A
    We know that A+B +20 = C
    We need to solve for A

    If A+B+C =500 units, then by substitution, A + [2A] + [A+ 2A + 20]=500
    A+2A+3A +20=500
    6A=500-20 so 6A=480 and therefore A=80

    So A=80 units, B=160 units and C=260 units
    80+160+260=500 units
