    Lighting Fixtures

    An apprentice unpacked 12 dozen fragile lighting fixtures. He was to receive $3 for each fixture that he unpacked safely and he agreed to pay $25 for every one that he broke. If the amount due him for his work was $236, how many did he break?

    Re :

    I got 2 equations here .
    Let x be the number of successful lightning fixtures
    Let y be the number of broken lightning fixtures .

    12 dozen = 144

    x+y=144 ---- 1
    3x-25y=236 ------ 2

    Solve for y ..
