Answer 1

Hello there!

In your question, we are trying to find the total amount of money raised when the money is rounded to the nearest thousands.

Answer: (3) 270,315

In order to solve the problem, we would need to round the money raised to the thousands place.

The thousands place would be the number before the comma. (_),000.

Lets round for Part A:

89,351. The thousands place would be 9 in this case, when you look at the number to the right of it (3), it's not big enough to make 9 bigger, so we would keep the thousands place the same. It would end up as 89,000.

102,459. The thousands place would be 2, the number to the right of it is not big enough to be rounded up, so we would keep it the same. It would end up as 102,000.

78,505. The thousands place would be 8. The number to the right of it is a big enough number to let the number 8 be rounded, therefore we would round the 8 up to 9. It would end up as 79,000.

Part B

Our current values would be 89,000, 102,000, and 79,000.

Now, for part B, we would add the rounded values to get an estimate of the money saved:

$89,000+102,000+79,000 =270,000$

You should get 270,000. Remember, that's just an estimate number.

Part C:

The answer choice that's close to that number is answer choice (3), $270,315.

Your FINAL answer should be (3) $270,315.
