To estimate a $$ 5\% $$ tip on a bill of $$ \$ 83.71 $$, we can follow these steps:

1. **Round the bill amount to the nearest ten dollars**:
   - The bill amount is $$ \$ 83.71 $$.
   - Rounding $$ 83.71 $$ to the nearest ten dollars gives us $$ 80 $$ (since $$ 83.71 $$ is closer to $$ 80 $$ than to $$ 90 $$).

2. **Calculate $$ 5\% $$ of the rounded amount**:
   - To find $$ 5\% $$ of $$ 80 $$, we can use the formula:
     $$
     \text{Tip} = \frac{5}{100} \times \text{Rounded Amount}
     $$
   - Substituting the rounded amount:
     $$
     \text{Tip} = \frac{5}{100} \times 80
     $$

Now, let's calculate this value.

$$
\text{Tip} = 0.05 \times 80 = 4
$$

Thus, the estimated $$ 5\% $$ tip on a bill of $$ \$ 83.71 $$ is approximately $$ \$ 4 $$.
To estimate a $$ 5\% $$ tip on a bill of $$ \$83.71 $$, round the bill to the nearest ten dollars (\$80) and calculate $$ 5\% $$ of \$80, which is \$4.

Percents Estimating a tip without a ceafculator Estimate a \( 5 \% \) tip on a bill of \( \$ 83.71 \) by first rounding the bill amount to the nearest ten dollars.
