Core Finance Principles
1 Budgeting Principle
Budgeting:
A budget is a plan for how to spend your money. It helps you decide how much to save and how much to spend.
Key Concepts:

Budget: Income - Expenses = Savings

Example Problem
Emma receives $10 as allowance each week. She spends $3 on snacks and saves the rest. How much does she save in 4 weeks?
Solution Steps:
  1. Calculate weekly savings: $10 - $3 = $7
  2. Calculate savings over 4 weeks: $7 × 4 = $28
  3. Verify: $3 × 4 = $12 spent, $28 saved, $12 + $28 = $40 earned
Weekly Income
$10
Weekly Expense
$3
Weekly Savings
$7
Step 1: Calculate weekly savings

Weekly savings = Income - Expenses = $10 - $3 = $7

Step 2: Calculate total savings

Total savings = Weekly savings × Number of weeks = $7 × 4 = $28

Step 3: Verify the answer

Spent: $3 × 4 = $12, Saved: $28, Total: $12 + $28 = $40

Earned: $10 × 4 = $40 ✓

Emma saves $28 in 4 weeks
Final Answer:

Emma saves $28 in 4 weeks.

Applied Rules:

• Budget equation: Income = Expenses + Savings

• Multiplication: repeated addition

• Verification: check if all parts add up to total

2 Making Change
Making Change:
When you pay with more money than the item costs, the store gives you back the difference. This is called change.
Key Concepts:

Change: Amount paid - Cost of items = Change

Example Problem
Tom buys a toy for $4.75 and pays with a $10 bill. How much change should he receive?
Amount Paid
$10.00
Item Cost
$4.75
Change
$5.25
Step 1: Align decimal points

$10.00 - $4.75

Step 2: Subtract cents

0¢ - 75¢ = Need to borrow: 100¢ - 75¢ = 25¢

Step 3: Subtract dollars

$9 - $4 = $5

Step 4: Combine results

$5 + 25¢ = $5.25

Step 5: Verify calculation

$4.75 + $5.25 = $10.00 ✓

Change = $5.25
Final Answer:

Tom should receive $5.25 in change.

Applied Rules:

• Change = Amount paid - Cost of items

• Align decimal points when subtracting money

• Verify by adding change to cost

3 Financial Planning
Financial Planning:
Financial planning involves setting goals and creating strategies to achieve them. It includes saving, spending, and budgeting.
Key Concepts:

Financial Goal: Something you want to save money for, like a toy or game.

Example Problem
Sarah wants to buy a bike that costs $80. She already has $25 saved and earns $5 per week from her allowance. How many weeks will it take her to save enough money?
Goal
$80
Already Saved
$25
Weekly Earnings
$5
Step 1: Calculate amount needed

Amount needed = Goal - Already saved = $80 - $25 = $55

Step 2: Calculate number of weeks

Weeks needed = Amount needed ÷ Weekly earnings = $55 ÷ $5 = 11 weeks

Step 3: Verify calculation

$25 + ($5 × 11) = $25 + $55 = $80 ✓

11 weeks needed
Final Answer:

Sarah needs 11 weeks to save enough money for the bike.

Applied Rules:

• Amount needed = Goal - Current savings

• Time needed = Amount needed ÷ Weekly earnings

• Verify by checking if total equals goal

DECA Competencies & Skills
4 Financial Decision Making
Financial Decision Making:
Making good financial decisions involves comparing costs, benefits, and alternatives before making a purchase.
Example Problem
Store A sells juice for $2.50 per bottle. Store B sells the same juice for $1.95 per bottle. If you buy 5 bottles, how much would you save by shopping at Store B?
Key Concepts:

Comparison Shopping: Finding the best deal by comparing prices at different stores.

Store A Cost
$12.50
Store B Cost
$9.75
Savings
$2.75
Step 1: Calculate cost at Store A

Store A: $2.50 × 5 = $12.50

Step 2: Calculate cost at Store B

Store B: $1.95 × 5 = $9.75

Step 3: Find the difference

Savings = $12.50 - $9.75 = $2.75

Step 4: Verify calculation

$9.75 + $2.75 = $12.50 ✓

Savings = $2.75
Final Answer:

You would save $2.75 by shopping at Store B.

Applied Rules:

• Calculate total cost for each option

• Subtract the lower cost from the higher cost to find savings

• Comparison shopping helps save money

5 Money Management
Money Management:
Money management involves tracking income and expenses, budgeting, and making smart financial choices.
Example Problem
Maya earned $15 from doing chores, $10 from helping neighbors, and $5 from selling old toys. She spent $12 on books and $8 on games. How much money does she have left?
Key Concepts:

Income Tracking: Recording all money received.

Expense Tracking: Recording all money spent.

Total Income
$30
Total Expenses
$20
Money Left
$10
Step 1: Calculate total income

Total income = $15 + $10 + $5 = $30

Step 2: Calculate total expenses

Total expenses = $12 + $8 = $20

Step 3: Calculate money left

Money left = Income - Expenses = $30 - $20 = $10

Step 4: Verify calculation

$20 + $10 = $30 ✓

Money left = $10
Final Answer:

Maya has $10 left.

Applied Rules:

• Track all income sources

• Track all expenses

• Money left = Total income - Total expenses
