Elena Woodward · Answer 1

457 sand dollars

Step-by-step explanation:

Let the number=x

The number she has collected is greater than 400 and less than 460

400
The number in hundreds place is one less than the number in the tens place.

The number in the Hundreds place is 4. Since it is one less, our number for now will be of the form 45 * where * is the ones digit.

Also, the number in the ones place is two more than the number in the tens place.

The number in the tens place is 5. If it is two more than 5, the number in the ones place is 7.

Therefore Chelsea has collected 457 sand dollars
