Answer:

#1/16# of a cup of olive oil per person.

Explanation:

The #3 3/4# cups are for 20 people.

The amount of dressing for one person is:

#3 3/4 div 20/1#

#= 15/4 xx1/20#

#= cancel15^3/4 xx1/cancel20^4#

=#3/16# cup per person.

#1/8# of this is lemon juice, the rest is olive oil.

#3/16-1/8#

#=3/16-2/16#

=#1/16# of a cup of olive oil per person.
