Christina Has Recently Graduated from College and Is Trying to Determine

Christina has recently graduated from college and is trying to determine how much she can afford to pay towards car payment. She would love to buy a new car rather than lease or take public transportation, so a budget is crucial to achieving this goal. She has just been offered a job at a local accounting firm where she will take home $3,400 per month after taxes. She has the opportunity to work as a freelance bookkeeper in her spare time where she will earn an additional $20 per hour after taxes. She believes that she can work 2 extra hours per week for a total of 8 hours per month. Her monthly expenses include the following: Phone, $100; Internet, $45; Rent (her share, including utilities), $1,100; Metro/Bus Fare, $33; Groceries and Household Supplies, $460; Additional Items are: Eating Out and Entertainment, $180; and Student Loans, $925. Using zero-based budgeting, answer the following questions.
a. How much of a car payment could Christina afford only with just the income from her full-time job?
b. How much of a car payment could Christina afford working at both her full-time job and as a freelance bookkeeper?
c. If Christina would like to buy a new car in cash for an amount of $20,000, then how many months would it take for her to save up for this goal with just the income from her full-time job?
