    Nope. Fred's earned value after 3 weeks is $95 and George's is $145.

    Step-by-step explanation:

    Fred:

    Substitute x with 3.

    45 (3) - 40

    Solve.

    = 135-40

    = 95

    George:

    Same as before, substitute x with 3.

    85 (3) - 110

    Solve.

    = 255-110

    = 145

    ---

    95 does no equal 145.
