10 Advanced problem solving
Exercise 10
A toy store counted its inventory: 15 action figures, 8 dolls, 12 cars, 9 puzzles, and 6 board games. If they sell 4 action figures and 3 cars, how many toys are left in the store?
Definition:

Multi-step data problem: A problem that requires multiple operations to solve, such as first collecting and organizing data, then performing addition and subtraction to find the final answer.

Note: These problems combine data collection skills with arithmetic operations to solve real-world scenarios.

Step-by-step multi-step method:
  1. Identify all the categories and their initial counts
  2. Calculate the total initial count
  3. Identify which items were sold and subtract them
  4. Calculate the final total after subtraction
Initial Inventory
15+8+12+9+6 = 50 toys
Items Sold
4+3 = 7 toys
Final Count
50-7 = 43 toys
Step 1: Organize the initial inventory

Action figures: 15, Dolls: 8, Cars: 12, Puzzles: 9, Board games: 6

Step 2: Calculate the total initial count

15 + 8 + 12 + 9 + 6 = 40

Wait, let me recalculate: 15 + 8 = 23, 23 + 12 = 35, 35 + 9 = 44, 44 + 6 = 50

Total initial toys: 50

Step 3: Identify items sold

Sold: 4 action figures and 3 cars

Total sold: 4 + 3 = 7 toys

Step 4: Calculate the final count

Remaining toys = Initial count - Sold items

Remaining toys = 50 - 7 = 43

43 toys remain in the store
Final answer:

There are 43 toys left in the store after selling 4 action figures and 3 cars (50 - 7 = 43).

Applied rules:

• Inventory calculation: Add all items to find initial total

• Subtraction: Subtract sold items from initial total
