    18 weeks

    Step-by-step explanation:

    Total amount of money saved up to buy the printer is T (w), where w is the number of weeks.

    Then T (w) = $100 + ($20/wk) w

    Setting this equal to $460, we solve the resulting equation for w to determine the number of weeks it took Hugo to save up $460 total:

    $460 = $100 + ($20/wk) w, or

    $360 = ($20/wk) w, or

    w = $360 / ($20/wk) = 18 weeks
