Which value for x completes the conditional relative frequency table by column? (i think its .85)

For the adult column we have the following equation:
 x + 0.15 = 1
 From here, we must clear the value of x.
 Clearing we have:
 x = 1-0.15
 x = 0.85
 Therefore, we have 85% of adults who like the new color of the paint.
 
 The value of x is:
 x = 0.85
