Mel Snow is the manager of a firm, Taxation Matters, which specialises in the preparation of income tax returns. The firm offers two basic products: the preparation of income tax returns for wage and salary earners, and the preparation of income tax returns for small businesses. Any clients requiringmore complex services are referred to Snow's brother Roger, who is a partner in a large firm ofchartered accountants.

The processing of wage and salary tax returns is quite straightforward, and the firm uses a software package to process data and print the return. A software package is also used to prepare returns for small businesses, although more information is required, particularly about business expenses.

Snow has only recently joined Taxation Matters and he is concerned about the firm's pricing policy,which sets flat fees of $60 per return for wage and salary clients and $300 for small businesses. He decides to use activity-based costing to estimate the costs of providing each of these services.

At the end of the year, Snow reviewed the firm's total costs and activities, resulting in the followinglist:
