Answer :
To estimate the amount of the tip on a bill of [tex]$405.96 by rounding the bill to the nearest ten dollars before calculating, follow these steps:
1. Round the Bill Amount:
First, take the given bill amount of $[/tex]405.96 and round it to the nearest ten dollars.
- [tex]$405.96 rounds up to $[/tex]410.
2. Calculate the Tip Percentage:
Next, calculate 15% of the rounded bill amount.
- 15% as a decimal is 0.15.
- Multiply the rounded bill amount by 0.15 to find the tip.
3. Perform the Calculation:
- Rounded bill amount: [tex]$410 - Tip percentage: 0.15 - Tip amount: \( 410 \times 0.15 = 61.5 \) Therefore, the amount of the tip is approximately \( \$[/tex]61.50 \).
- [tex]$405.96 rounds up to $[/tex]410.
2. Calculate the Tip Percentage:
Next, calculate 15% of the rounded bill amount.
- 15% as a decimal is 0.15.
- Multiply the rounded bill amount by 0.15 to find the tip.
3. Perform the Calculation:
- Rounded bill amount: [tex]$410 - Tip percentage: 0.15 - Tip amount: \( 410 \times 0.15 = 61.5 \) Therefore, the amount of the tip is approximately \( \$[/tex]61.50 \).
