This project involves devising and evaluating a sales tax schedule to meet the specific revenue needs of a hypothetical state in the United States. Conducting this unit involves many mathematical skills in a learning environment familiar to the student. The essential parts of the project consist of student preparation of a tax schedule and class participation in evaluating the proposals of others. Mathematical operations involve arithmetic computations (including computation of percent), construction of tables, formulae, rounding, graphing, and employment of random numbers. (Author/MK)
