#30#

Explanation:

the range of scores is #11#.

the range of scores is the range between the lowest score and the highest score.

the range between the lowest and highest score is the difference between them, i.e. highest score - lowest score.

range = highest score - lowest score

highest score = range + lowest score

range + lowest score = #11 + 19#

#=30#

the highest score is #30#.
