    Minimum number of complete hours he has to work=12 hours

    Step-by-step explanation:

    The total amount of money he needs can be expressed by the equation;

    Total amount he needs=Amount saved+Amount he makes an hour.

    Where;

    Total amount he needs=$125

    Amount saved=$45

    Amount he makes an hour=$7*Number of hours (h) = 7h

    Substituting in the expression above;

    125=45+7h

    7h = (125-45)

    7h/7=80/7

    h=11.43 hours

    Minimum number of hours he has to work=11.43 hours

    Minimum number of complete hours he has to work=12 hours
