To find the missing values, we can use the formula: Total = row total = column total. 
For the row "Open", the total is 100. So, 31 + 42 + xx = 100, which gives xx = 27.
For the column "Low", the total is 198. So, 58 + yy = 198, which gives yy = 140.
Therefore, the missing values are xx = 27 and yy = 140. 
Option C is the only one that has xx = 27 as an option.
