Lily has $18. matt has twice as much of a third of the amount lily has, and carolyn has $23 more than matt has. how much money does carolyn have?

Carolyn have 35 dollars

Okay,

A third of $18, is $6
and if he has twice the amount of a third of 18 dollars
that equation would be 2 * 6 
Which would equal $12
So Matt has $12

Carolyn has $23 more dollars than Matt
12 + 23 = 35

So your answer would be:
Carolyn has $35
