    Answer: 16 hours

    Step-by-step explanation:

    The two equations are:

    840 + 17x

    and

    760 + 22x

    with x being the amount of hours

    840 + 17x = 760 + 22x  

    -760

    80 + 17x = 22x

    -17x

    80 = 5x

    /5

    16 = x

    840 + 17(16) = 1,112

    760 + 22(16) = 1,112
