Money Machine Price Exercises 1-3
1 Price Comparison
Exercise 1
A basic money counting machine costs $35.00. A deluxe model costs $55.00. How much more expensive is the deluxe model? If you have $40.00, which one can you afford?
Price Analysis:

Comparing different price points and affordability.

Definition:

Price difference: The amount more one item costs compared to another

Step-by-step method:
  1. Identify the prices of both items
  2. Subtract the lower price from the higher price
  3. Check your budget against each price
  4. Determine what you can afford
Step 1: Identify the prices

Basic model = $35.00, Deluxe model = $55.00

Step 2: Calculate the price difference

$55.00 - $35.00 = $20.00

Step 3: Check affordability

You have $40.00

Basic model: $40.00 > $35.00 ✓ (affordable)

Deluxe model: $40.00 < $55.00 ✗ (not affordable)

Difference = $20.00, Basic = Affordable
Final answer:

The deluxe model is $20.00 more expensive than the basic model. With $40.00, you can afford the basic model but not the deluxe one.

Applied rules:

• Subtraction: Higher price - Lower price = Difference

• Comparison: Check if money ≥ price

• Budget awareness: Know your spending limits

2 Budget Planning
Exercise 2
You have saved $60.00 to buy a money counting machine. The store offers three models: $35.00, $50.00, and $75.00. Which models can you afford? How much change would you get from each affordable option?
Price Analysis:

Planning purchases within your budget constraints.

Definition:

Budget planning: Deciding what you can afford based on available money

Step 1: List all prices and budget

Models: $35.00, $50.00, $75.00

Budget: $60.00

Step 2: Check affordability for each model

Model 1: $35.00 ≤ $60.00 ✓ (affordable)

Model 2: $50.00 ≤ $60.00 ✓ (affordable)

Model 3: $75.00 > $60.00 ✗ (not affordable)

Step 3: Calculate change for affordable models

Model 1: $60.00 - $35.00 = $25.00 change

Model 2: $60.00 - $50.00 = $10.00 change

Affordable: $35.00 and $50.00 models
Final answer:

You can afford the $35.00 and $50.00 models. You'd get $25.00 change from the cheaper model or $10.00 change from the middle-priced model.

Applied rules:

• Affordability check: Money ≥ Price

• Change calculation: Budget - Price = Change

• Multiple options: Evaluate all affordable choices

3 Saving for Purchase
Exercise 3
A money counting machine costs $48.00. You currently have $23.00 saved. How much more money do you need to save? If you save $5.00 per week, how many weeks will it take to afford the machine?
Price Analysis:

Calculating savings goals and timeframes for purchases.

Definition:

Savings goal: The amount of money needed to purchase an item

Step 1: Calculate money needed

Machine cost = $48.00

Money saved = $23.00

Money needed = $48.00 - $23.00 = $25.00

Step 2: Calculate weeks to save

Weekly savings = $5.00

Weeks needed = $25.00 ÷ $5.00 = 5 weeks

Need $25.00 more, 5 weeks to save
Final answer:

You need to save $25.00 more to buy the machine. At $5.00 per week, it will take 5 weeks to save enough money.

Applied rules:

• Money needed: Price - Saved = Amount needed

• Time calculation: Amount needed ÷ Weekly savings = Weeks needed

• Planning: Set achievable savings goals

Money Machine Price Exercises 4-5
4 Feature Comparison
Exercise 4
Store A sells a money counting machine for $42.00 with a $3.00 discount. Store B sells the same machine for $39.00 but charges $5.00 for delivery. Which store offers the better deal? What is the total cost at each store?
Price Analysis:

Evaluating total costs including discounts and additional fees.

Definition:

Total cost: The complete amount paid including all fees and after discounts

Step 1: Calculate Store A's total

Original price = $42.00

Discount = $3.00

Store A total = $42.00 - $3.00 = $39.00

Step 2: Calculate Store B's total

Base price = $39.00

Delivery fee = $5.00

Store B total = $39.00 + $5.00 = $44.00

Step 3: Compare and decide

Store A: $39.00 vs Store B: $44.00

Store A is cheaper by $5.00

Store A: $39.00, Store B: $44.00
Final answer:

Store A offers the better deal at $39.00 compared to Store B's $44.00. Store A saves you $5.00.

Applied rules:

• Net pricing: Account for discounts and additional fees

• Total comparison: Compare final amounts, not base prices

• Value assessment: Consider all costs in decision-making

5 Bundle Deal Analysis
Exercise 5
A money counting machine costs $55.00. A bundle deal includes the machine plus a coin sorter for $65.00. The coin sorter alone costs $18.00. Is the bundle a good deal? How much would you save by buying the bundle instead of items separately?
Price Analysis:

Evaluating bundle deals versus individual purchases.

Definition:

Bundle value: The benefit of purchasing multiple items together versus separately

Step 1: Calculate separate purchase cost

Machine = $55.00

Coin sorter = $18.00

Separate total = $55.00 + $18.00 = $73.00

Step 2: Compare bundle price

Bundle price = $65.00

Separate price = $73.00

Step 3: Calculate savings

Savings = $73.00 - $65.00 = $8.00

Yes, save $8.00 with bundle
Final answer:

Yes, the bundle is a good deal. Buying separately would cost $73.00, but the bundle costs $65.00, saving you $8.00.

Applied rules:

• Bundle evaluation: Calculate total cost of individual items

• Savings calculation: Separate cost - Bundle cost = Savings

• Value assessment: Determine if savings justify the bundle
