4. Preparing a cesh budget Brock and Sam started to create a budget (based on last year's income and expense statement) but got stuck. They know that you have learned how to create budgets and are asking for your help. They would like you to input the correct values for the first three months of next year. In addition to the statement, you will need to know the following information: - They estimated their net annual income (after taxes and employer deductions) at \$15,000 for Brock and $13,500 for $am - Insurance is paid at the end of each calendar quarter - Sam purchases her commuter pass on the first of each month - The parents' loan is money they borrowed from Sam's parents to pay off their student loans. How much they pay each month is determined by them - The fun money listed on the statement is the money spent for a cruise to Mexico.
