Now that operations for outdoor clinics and TEAM events are running smoothly, Suzie thinks of another area for business expansion. She notices that a few clinic participants wear multiuse (MU) watches. Beyond the normal timekeeping features of most watches, MU watches are able to report temperature, altitude, and barometric pressure. MU watches are waterproof, so moisture from kayaking, rain, fishing, or even diving up to 100 feet wont damage them. Suzie decides to have MU watches available for sale at the start of each clinic.

The following transactions relate to purchases and sales of watches during the second half of 2019. All watches are sold for $307 each.
