let
x------------> a birthday dinner at a restaurant, including a 15% tip.

we know that

Kristin decides to spend at most $50
so
x <= $50

the answer part a) is
x <= 50

Part b) What is the most that her meal can cost before a tip?

the tip is 15%
so
cost after tip=1.15*cost before a tip
cost before a tip=cost after tip/1.15
50/1.15-------> $43.48

the answer part b) is 
$43.48
