In her classroom, Mrs. Martin has a box full of regular pencils and colored pencils. There are 54 more colored pencils than regular pencils. If the box has 87 regular pencils, how many pencils are there in all?

To solve this problem, we can break it down step by step.

1. **Determine the number of colored pencils**:  
   The problem states that there are 54 more colored pencils than regular pencils.  
   Since there are 87 regular pencils, the number of colored pencils is:
   \[
   87 + 54 = 141 \text{ colored pencils}
   \]

2. **Find the total number of pencils**:  
   To find the total number of pencils in the box, add the number of regular pencils to the number of colored pencils:
   \[
   87 + 141 = 228 \text{ pencils in total}
   \]

So, there are **228 pencils** in all.

2. What would the total number of pencils be if the difference between regular and colored pencils was 30 instead of 54?
3. How many regular pencils would be needed to have a total of 300 pencils, given the same difference of 54 more colored pencils?
4. What if there were twice as many colored pencils as regular pencils? How many colored pencils would that be?
5. If Mrs. Martin gave away 20 regular pencils, how many pencils would remain in the box?
