Estimate a 15% tip on a dinner bill of $38.41 by first rounding the bill amount to the nearest ten dollars.

Answer 1

To estimate a 15% tip on a dinner bill of $38.41 by rounding the bill amount to the nearest ten dollars:

1. Round the bill amount: $38.41 rounds to $40 (the nearest ten).

2. Calculate 15% of the rounded amount:

   • 10% of $40 is $4.
   • 5% of $40 is half of $4, which is $2.
   • Therefore, 15% of $40 is $4 + $2 = $6.

Thus, the estimated tip is $6.
