Mr Cervantes drove 3156 miles in December and 8099 miles in January select all choices that are good estimates for the total number of miles Mr Cervantes drove for both months by rounding by place value

1 answer

The total number of miles Mr. Cervantes drove for both months can be estimated by rounding each monthly total to the nearest hundred, thousand, or ten thousand.

Rounded to the nearest hundred:
December: 3200 miles
January: 8100 miles

Rounded to the nearest thousand:
December: 3000 miles
January: 8000 miles

Rounded to the nearest ten thousand:
December: 0 miles
January: 0 miles

So the good estimates for the total number of miles Mr. Cervantes drove for both months are:
- 3200 + 8100 = 11,300 miles (rounded to the nearest hundred)
- 3000 + 8000 = 11,000 miles (rounded to the nearest thousand)
