Peter had $734.07. He spent $106.49 during a short visit to the doctor. Round the amount to the nearest ten dollars. About how much money is left with him?
A. $620
B. $840
C. $627
D. $600
$734.07 - $106.49 = 627.58 ; C
The question asked for the rounded answer to the nearest 10 dollars.
$627.58 to the nearest $10 is $630 , which is not in your list of answers.
That's odd, I just noticed that. So then I guess C would be correct either way.
Apparently the answer is A ; $620. That's super weird. I don't get this problem at all.
To solve this problem, you need to subtract the amount Peter spent from the initial amount he had.
1. Start with the initial amount Peter had: $734.07.
2. Subtract the amount he spent: $734.07 - $106.49 = $627.58.
Now, to round this amount to the nearest ten dollars, you look at the digit in the ones place (the tenths place). Since the digit is greater than or equal to 5 (8 in this case), you round up the tens place.
3. Round the amount to the nearest ten dollars: $630.
Therefore, Peter has about $630 left with him.
Among the given options, the closest answer is C. $627, which is the rounded value of $630.
