Ziffel McSporran is a provider of de-icing goods and services for Fern Tree, a suburb of Hobart that often has its roads blocked by snow in the winter. Customers may choose to purchase a high-tech, solar augmented electric snow shovel for $480.00. They may also choose to subscribe to a snow cleaning service which costs $800.00 and covers the months of June to September inclusive. However, as having snow shovels on location can make McSporran's service more efficient, he also provides a combined 'new customer' package whereby a customer obtains the snow shovel together with a 4-month service for the first year for the total package price of $960.00. McSporran's financial year ends on 30th June.

3. Following from part 2 what adjusting entry would be necessary on the 30th of June?
