On July $15,$ Year $1,$ Balance & Company signed a contract to provide Pastry Bakery with an ingredient$-$weighing system for a price of $$90,000.$ The system included finely tuned scales that fit into Pastry$$s automated assembly line, Balance$$s proprietary software modified to allow the weighing system to function in Pastry$$s automated system, and a one$-$year contract to calibrate the equipment and software on an as$-$needed basis. Balance$$s scales will only work with its proprietary software, and that software is not usable with other weighing systems. $($Balance competes with other vendors who offer ongoing calibration contracts for Balance$$s systems.$)$ If Balance was to provide these goods or services separately, it would charge $$60,000$ for the scales, $$10,000$ for the software, and $$30,000$ for the calibration contract. Balance delivered and installed the equipment and software on August $1,$ Year $1,$ and the calibration service commenced on that date. How many performance obligations exist in this contract?
