Explanation:

Step1: Round the bill to nearest dollar

The bill is $64.75. When rounding to the nearest dollar, look at the decimal part. Since 0.75 ≥ 0.5, we round up. So $64.75 rounded to the nearest dollar is $65.

Step2: Calculate 20% of the rounded bill

To find 20% of a number, we can convert 20% to a decimal (0.2) and multiply by the number. So, 20% of $65 is $65\times0.2$.
$65\times0.2 = 13$

Answer:

13
