Sure! Here is a word problem that can be represented by the algebraic expression y - 95: "Sarah had y dollars in her savings account. She spent $95 on a new dress. Write an expression to represent how much money she has left in her account." If y equals 125, we can evaluate the expression y - 95 by substituting y with 125: 125 - 95 = 30 Therefore, Sarah has $30 left in her savings account after buying the dress.
