Comparison: Compare total money with cost to determine if purchase is possible
If Total Money ≥ Cost, then purchase is possible
5. Tom has 12 quarters, 8 dimes, 15 nickels, and 23 pennies. He wants to buy a tool that costs $4.95. Does he have enough money? If yes, how much change will he get?
Show your work:
Quarters value: _________
Dimes value: _________
Nickels value: _________
Pennies value: _________
Total money: ___________
Cost of tool: _________
Answer: _____________
Quarters value: 12 × $0.25 = $3.00
Dimes value: 8 × $0.10 = $0.80
Nickels value: 15 × $0.05 = $0.75
Pennies value: 23 × $0.01 = $0.23
Total money: $3.00 + $0.80 + $0.75 + $0.23 = $4.78
Cost of tool: $4.95
Answer: No, he does not have enough money. He needs $4.95 - $4.78 = $0.17 more.
Currency Conversion: Calculate total value of different coin types
Calculate value of each coin type separately, then add together
6. A customer pays $20.00 for an item that costs $13.87. What is the most efficient way to give the change using the fewest coins possible? Include dollar bills and coins.
Show your work:
Calculation: ___________
Most efficient way: ___________
Answer: _____________
Calculation: $20.00 - $13.87 = $6.13
Most efficient way: 6 dollar bills + 1 dime + 1 nickel + 3 pennies = $6.00 + $0.10 + $0.05 + $0.03 = $6.13
Answer: The most efficient way is 6 dollar bills + 1 dime + 1 nickel + 3 pennies (11 total bills and coins).
Efficiency: Using the fewest coins/bills possible to make change
Always start with the largest denomination first
7. Scenario A: Buy a pen for $1.95 with $5.00. Scenario B: Buy a notebook for $3.25 with $10.00. Scenario C: Buy a calculator for $7.80 with $20.00. Which scenario gives the most change? How much more than the others?
Show your work:
Scenario A calculation: ___________
Scenario B calculation: ___________
Scenario C calculation: ___________
Comparison: ___________
Answer: _____________
Scenario A: $5.00 - $1.95 = $3.05
Scenario B: $10.00 - $3.25 = $6.75
Scenario C: $20.00 - $7.80 = $12.20
Comparison: Scenario C gives the most change. It gives $12.20 - $6.75 = $5.45 more than Scenario B and $12.20 - $3.05 = $9.15 more than Scenario A.
Answer: Scenario C gives the most change at $12.20.
Comparison: Calculating and comparing different change amounts
Calculate each scenario separately, then compare the results
