Designed to help Engineering students to learn Engineering Economics. Tools include an E-book with key concepts and video links, common formulas and interest tables. Conceptual questions and practice problems are presented in a Jeopardy! game style. The problems range from the simple questions on time values of money, to Sensitivity Analysis, to Monte Carlo Simulation and to Supply Demand Equilibrium. Complex problems are accompanied by graphical plots. The mobile app development is sponsored by National Science Foundation (Grant DUE-1140457), USA.
