Dorothy acquired a 100% interest in two passive activities: Activity A in January 2011 and Activity B in 2012. Through 2014, Activity A was profitable, but it produced losses of $200,000 in 2015 and $100,000 in 2016. Dorothy has passive activity income from Activity B of $20,000 in 2015 and $40,000 in 2016. After offsetting passive activity income, how much of the net losses may she deduct?
