Final answer:

To find the mystery number, we need to consider all the clues. The number that satisfies all the given clues is 582.

Step-by-step explanation:

To find the mystery number, we need to consider all the clues. Clue #1 tells us that the number is greater than 500. Clue #2 informs us that the hundreds digit is even, so it could be 5, 6, or 8. Clue #3 states that 20 base ten blocks are used to show the number, with 5 of them being tens blocks. Finally, Clue #4 mentions that there are 4 more ones blocks than tens blocks.

Based on these clues, the only option that satisfies all of them is option c. 582. Let's break it down:

  • Hundreds digit is even: Yes, 5 is even.
  • Greater than 500: Yes, 582 is greater.
  • 20 base ten blocks with 5 tens blocks: 582 has 5 tens blocks.
  • 4 more ones blocks than tens blocks: 582 has 4 + 5 = 9 ones blocks.

Therefore, the mystery number is 582.
