Will lives 8 blocks from school. He just left school and walked 

b

 blocks toward home. Write an expression that shows the number of blocks remaining.

Submit


To find the number of blocks Will has left to walk to get home, we subtract the number of blocks he has already walked from the total number of blocks between his school and home.

Let \( b \) represent the number of blocks Will has walked toward home. The total number of blocks from school to home is 8. The expression for the number of blocks remaining for Will to walk is:

\[
8 - b
\]

**Relative Questions:**

1. If Will has walked 3 blocks, how many blocks does he have left to walk?
2. What would the expression look like if the total distance was 10 blocks instead of 8?
3. If \( b = 8 \), what does the expression \( 8 - b \) equal, and what does that mean in this context?
4. What happens if \( b \) is greater than 8?
5. How would you describe the relationship between \( b \) and the number of blocks remaining?
6. What is the domain of the expression \( 8 - b \) in the context of this problem?
7. If Will stops to rest after walking \( b \) blocks, how would you describe his remaining journey?
8. How could this expression change if Will were to start walking from home towards the school instead?

**Tip:** When solving problems involving subtraction of quantities, ensure the starting amount (in this case, total blocks) is larger than the subtracted amount to avoid negative values in a real-world context.
