To estimate $6.56 + $13.02 using front-end estimation, you can round each number to their nearest tens place and then perform the addition. Here's how you can do it:
1. Round $6.56 to the nearest tens place: Since the digit in the ones place is less than 5, the tens place remains the same. So, $6.56 rounds to $10.00.
2. Round $13.02 to the nearest tens place: The digit in the ones place is 2, which is less than 5. So, the tens place remains the same. Therefore, $13.02 rounds to $10.00.
3. Add the rounded numbers: $10.00 + $10.00 = $20.00
So, by using front-end estimation, the sum of $6.56 + $13.02 is approximately $20.00. Therefore, the closest option is "about $20.10".
