Problem:
Aztec Furnishings makes hand-crafted furniture for sale in its retail stores. The furniture maker has recently installed a new assembly process, including a new sander and polisher. With this new system, production has increased to ninety pieces of furniture a day from the previous sixty pieces of furniture a day. The number of defective items produced has dropped from 10 pieces per day to 1 per day. The production facility operates strictly eight hours per day. Evaluate the change in productivity for Aztec using the new assembly process.
