Final answer:
Without Oscar's budget table, we cannot verify the statements related to his expenses and savings. For Mary Ann, however, her monthly after-tax income allows her to cover her expenses and meet her savings goal of 10%.
Step-by-step explanation:
To answer the student's question, we would need to reference Oscar's budget table; however, such a table is not provided. Therefore, we can't verify the statements related to Oscar's monthly income and budget allocations. For Mary Ann, who has an after-tax monthly income of $2,589.10 and wishes to save 10% of her income, we can construct a budget table based on her expenses and calculate her ability to save.
Mary Ann's monthly savings goal is 10% of $2,589.10, which equals $258.91. Summing up her given expenses: rent ($790), cell phone ($75), utilities ($45), cable TV and internet ($65), groceries ($450), entertainment ($250), car payment ($350), and gasoline ($120), we get a total expense of $2,145. Since her total expenses are less than her income, Mary Ann can meet her savings goal.
Constructing such a budget table is important for personal financial planning, as it can help ensure that expenses do not exceed income and that savings goals are met.
