A furniture builder will build a number of identical tables. The builder’s fee can be calculated by the expression tklw, where t is the number of tables, k is the cost of material per square foot, l is the length of each table, and w is the width of each table. If the customer asks the builder to make the tables shorter and wider, which of the factors in the expression would change?
