    To find the original cost of the shirt

    Let the original cost be x

    The markup percentage is 25%, which means the store is selling the shirt for 100% + 25% = 125% of the original cost.
    So now the equation is
    x + 25% of x = $40

    We can write 25% as 0.25

    So, x + 0.25x = $40

    1.25x = $40

    x = $40 / 1.25

    x = $32

    Therefore, the original cost of the shirt was $32.

    So, the correct answer is option c)$32.
