See a solution process below:

Explanation:

First, let's convert the "feet" to "inches" so we can work this problem in the same units:

#1" feet" = 12" inches"#

We can multiply each side of the equation by #color(red)(5)# to find how many inches of ribbon there are in #5# feet.

#color(red)(5) xx 1" feet" = color(red)(5) xx 12" inches"#

#5" feet" = 60" inches"#

So Vanessa started with 60 inches. We can no subtract off the two pieces of ribbon Vanessa used to find how much ribbon Vanessa has left:

#60" inches" - 36" inches" - 18" inches" =>#

#24" inches" - 18" inches" =>#

#6" inches"#

Vanessa should have 6 inches of ribbon remaining.
