T$$i set aside $4$ million VND for university preparation before enrolling. T$$i is now living with his parents. T$$i asked Ch$$nh$,$ a finance and banking$-$major friend, what he could do to better manage his money. Ch$$nh$\text{'}$s solution is to create a budget.

T$$i is asked to describe his goals and current spending habits. T$$i responded, "The cost of attending university is higher than I anticipated, and my parents expect me to be able to cover my own living expenses while attending university. I$\text{'}$m guessing around $40$ million VND per year! I've considered working parttime, but I$\text{'}$m not sure I can balance studying and working parttime. Budgeting appears to be a good idea, but I$\text{'}$m not sure where to begin$$
