The table shows the heights of Anna, Levi, and Isaiah. The average height of three children is 147 cm. The digit in the ones place of Anna's height and the digit in the tens place of Isaiah's height are covered by ink blots.
- What is the digit in the ones place of Anna's height?

319 - 150 - 106
= 63
