Jerry sold #20# tickets

We can add the tickets that Raul and Chris sold and subtract that quantity from #88#. The result is the amount of tickets that Jerry sold.

Thus,

#30+38=68#

#88-68=20larr# The amount of tickets that Jerry sold

We could have also written out an equation like this:

#30+38+t=88#, where #t# is the amount of tickets Jerry sold.

Solving for #t#...

#68+t-88#

Subtract #68# from both sides:

#68-68+t=88-68#

#t=20#
