To find the estimated tip amount, we need to follow a step-by-step approach:

1. Round the Bill to the Nearest Ten Dollars:
- The original bill amount is [tex]$469.85. - To round to the nearest ten dollars, look at the units digit (the digit right before the decimal point) of the bill amount. - Since the units digit, which is 9, is 5 or higher, we round up. - Therefore, $[/tex]469.85 rounds up to [tex]$470. 2. Determine the Tip Percentage: - The tip percentage specified is 15%. 3. Calculate the Tip Amount based on the Rounded Bill: - To find 15% of $[/tex]470, multiply [tex]$470 by 0.15. - The calculation is as follows: \[ Tip\ Amount = 470 \times 0.15 = 70.5 \] Based on these calculations, the estimated amount of the tip is approximately $[/tex]70.50.
