Master budget | Accounting homework help

Your first job assignment requires you to create a master budget. The details are
presented below.
Background
Apple Inc. manufacturers I-phones. You have been hired as a cost accountant and your
assignment to create a master budget using EXCEL.. You have been working with various
departments to gather financial data to assemble a master budget. One reason you have
chosen this format is that upper management will probably make some last-minute changes
to sales and possible changes to some other cost forecasts. So, to simplify this problem you
MUST link all the budgets together. For example, if you change the sales forecast, then all
the remaining numbers in all other budgets would change without having to change numbers
manually in each budget.
One quarter of the budget has been prepared for you but you need to input the other three
quarters in order to prepare the income statement.
Here are the steps:
1. You must setup all eight budgets using Excel. Starting with the sales budget, manually
calculate the sales budget forecast for all four quarters and calculate the total column
2.  Each budget should be prepared on individual Excel spreadsheets, on separate tabs.
3.  Each budget should professionally represent all the budget information; must be easy
to understand so it can be presented to the CEO and the owners of the business.
4. Briefly discuss your assumptions and any challenges you encountered while preparing
the budget.
