1. **Calculate the total amount of money mother gave:** - Three twenty-dollar bills: $3 \times 20 = 60$ - Four ten-dollar bills: $4 \times 10 = 40$ - Six twenty-five cent coins: $6 \times 0.25 = 1.50$ - Total money = $60 + 40 + 1.50 = 101.50$ 2. **Find how many more hundreds in 5,015 than in 2,162:** - Hundreds in 5,015: Integer division $\lfloor\frac{5015}{100}\rfloor = 50$ - Hundreds in 2,162: $\lfloor\frac{2162}{100}\rfloor = 21$ - Difference = $50 - 21 = 29$ 3. **Calculate the change from $300 after buying 2 shirts and shoes:** - Cost of 2 shirts: $2 \times 40.05 = 80.10$ - Cost of shoes: $65.75$ - Total cost = $80.10 + 65.75 = 145.85$ - Change = $300 - 145.85 = 154.15$ - Rounded to nearest dollar: $154$ 4. **Find the last 11 bills that sum to $367:** - We want 11 bills summing to $367. Assume bills are $1 each (simplest assumption without more info). - Since 11 bills at $1 each = $11 only, not $367, consider different bill types. - Likely bills include $20, $10, $5, or $1. - Example: 11 bills with 9 twenties and 2 sevens is impossible because 7 bills is not a usual bill. - So try mixed bills: 11 bills total, possible combination for $367 is 10 twenties ($200), 1 fifty ($50), but fifty not standard US bill. - More realistic: 11 bills with 8 twenties ($160), 2 tens ($20), 1 five ($5) totals $185, too low. - Another try: 11 twenties = $220 + 11 fives = $55 totals $275. - Without more info, problem is incomplete, thus answer is: The problem needs clarification or bill types to solve. 5. **Calculate more tens in 6,173 than in 5,173:** - Tens digit in 6,173 is 7 - Tens digit in 5,173 is 7 - Difference = $7 - 7 = 0$ 6. **Calculate difference when 6 in 71,612 is replaced by 4:** - Original number: 71,612 - New number: 71,412 - Difference: $71612 - 71412 = 200$ 7. **Write number representing 6 ten thousand, 4 hundred, 5 tens:** - $6 \times 10,000 = 60,000$ - $4 \times 100 = 400$ - $5 \times 10 = 50$ - Sum: $60,000 + 400 + 50 = 60,450$ 8. **Sum digits of 1 7 4 3 1 5 9 and write answer in words:** - Sum: $1 + 7 + 4 + 3 + 1 + 5 + 9 = 30$ - Answer in words: "thirty" 9. **Henry has 16 twenty-dollar bills. Calculate approximated money to nearest hundred:** - Total: $16 \times 20 = 320$ - Rounded to nearest hundred: $300$ 10. **Ramesh has 70. Find value of unmarked bill given bills $5, $10, $5, $10, and unknown:** - Sum known bills: $5 + 10 + 5 + 10 = 30$ - Total $70 - 30 = 40$ - Unmarked bill value is $40$ (likely representing a $20 and a $20 or other combination, but problem states a single bill so $40$ is answer)
