Answer Key

Section 2: Quick Calculations (Warm-up)

1. Calculation: $3.25 + $1.50 = $4.75 Total Cost: $4.75
2. Calculation: $5.00 - $0.75 = $4.25 Change Received: $4.25

Section 3: The Big Shopping Trip (Multi-Step Problems)

Problem A: Basic Purchase

1. Costs: $3.25, $1.50, $2.10
2. Calculation: $3.25 + $1.50 + $2.10 = $6.85 Total Expenditure: $6.85

Problem B: Buying in Bulk

1. Cost of Markers (2 x $6.00): $12.00
2. Cost of Erasers (4 x $0.75): $3.00
3. Calculation: $12.00 + $3.00 = $15.00 Grand Total: $15.00

Problem C: Sticking to the Budget

1. Total Cost: $3.25 (Notebook) + $6.00 (Markers) = $9.25
2. Calculation: $20.00 - $9.25 = $10.75 Remaining Budget: $10.75

Section 4: Budget Planning Activity (Answers will vary. Example shown below)

Section 5: The Team Challenge

1. Total Cost: 12 x $3.25 = $39.00
