Tyler's college fund had a balance of $1875 before he made deposits of $178, $225, and $590.

• After making the deposits, which is the best estimate for the balance in Tyler's college fund?

The correct answer to this one is D. Let's see how we solved it.

You begin by rounding each of the dollar values to their largest place value. Therefore, we arrive at this:

$1875 becomes $2000
$178 becomes $200
$225 becomes $200
$590 becomes $600

We continue by adding the four dollar values doing mental math and come up with an answer of $3000.

Therefore, we can answer the question in the problem with letter D, $3000, as the best estimate for Tyler's balance in his college fund.
