=+13-24 K Allocation of common costs OBJECTIVE 4 Angela Stonely, a self-employed consultant in Brisbane, received an invitation to visit a prospective client in Adelaide. A few days later, she received an invitation to make a presentation to a prospective client in Christchurch, New Zealand. She decided to combine her visits, travelling from Brisbane to Adelaide, and Adelaide to Christchurch.

Stonely received offers for her consulting services from both companies. Upon her return, she decided to accept the engagement in Adelaide. She is puzzled over how to allocate her travel costs between the two clients. She has collected the following data for regular return-trip fares with no stopovers:
