See a solution process below:

Explanation:

We can write the following relationship and then solve for #d#:

#d/100 = 1/0.88#

#color(red)(100) xx d/100 = color(red)(100) xx 1/0.88#

#cancel(color(red)(100)) xx d/color(red)(cancel(color(black)(100))) = 100/0.88#

#d = 113.636#

#d = $113.64#

Kelsey will need to give the bank #color(red)($113.64)# to get back 100 Euros.
