Budgeting & money management

Grade 9 · Math · Free lesson

Hey there! Ready to take control of your money? Let's explore how to synthesize different financial sources to build a perfect budget!

To manage money well, we must synthesize information from different sources. This means looking at our income, like a paycheck, and comparing it to our expenses, like bills and savings goals, to see the whole picture.

We can group our expenses into two main categories: fixed costs and variable costs. Fixed costs stay the same every month, like rent, while variable costs change, like groceries or entertainment.

Fixed: $120 Variable: $80

When we synthesize, we combine these sources to calculate our net savings. Subtracting all expenses from our total income shows us exactly how much money we have left to save for the future.

✏️ Worked example

Imagine you have two sources of information. Source A: A flyer for a part-time job showing you earn $150 per week. Source B: A list of weekly expenses, which includes $40 for bus fare (fixed) and $35 for snacks (variable). Synthesize this information to find out how much you can save each week.

  1. Identify the total weekly income from Source A, which is $150.
  2. Identify all weekly expenses from Source B, which are $40 (fixed) and $35 (variable).
  3. Add the expenses together to find the total cost: $40 + $35 = $75.
  4. Synthesize by subtracting the total expenses from the total income: $150 - $75 = $75.
  5. Conclude that you can save $75 each week by combining these sources.
