Fatima requires #$22.50# more in order to purchase the scarf and sweater.

Explanation:

The total cost #(x)# of the two items that Fatima wants to purchase is:

#x=45+77.50#

#x=122.50#

Since Fatima has #$100# with her, the amount #(y)# she requires to purchase those items is:

#y=122.50-100#

#y=22.50#
