The given statement is y < 7x4+3. To make this statement true, we need to find values of y that are less than the expression 7x4+3. By substituting the values of y given in the answer choices into the expression, we can determine which values satisfy the inequality. From the answer choices, y = 20, y = 28, and y = 0 are the values that make the statement true because they are all less than 7x4+3. Therefore, these are the correct answers.

The correct answer is 20,000+4,000+300+90+7. This is the expanded form of 24,397, where each digit is written in its place value position. The digit 2 is in the ten thousands place, so it is multiplied by 10,000. The digit 4 is in the thousands place, so it is multiplied by 1,000. The digit 3 is in the hundreds place, so it is multiplied by 100. The digit 9 is in the tens place, so it is multiplied by 10. The digit 7 is in the ones place, so it is not multiplied by anything. All of these values are then added together to get the expanded form of 24,397.
