Sure, let's pluralize the conversation step-by-step:
1. Which one [tex]$\rightarrow$[/tex] Which ones
- "one" changes to "ones" to indicate plurality.
- "Which" remains unchanged as both singular and plural.
2. The red one [tex]$\rightarrow$[/tex] The red ones
- "one" changes to "ones" to indicate more than one red item.
3. It is 20 dollars [tex]$\rightarrow$[/tex] They are 20 dollars
- "It" changes to "They" to account for the plural noun.
- "is" changes to "are" to agree with the plural subject "They."
4. And the black one? [tex]$\rightarrow$[/tex] And the black ones?
- "one" changes to "ones" which changes it to plural form.
5. It is 15 dollars. [tex]$\rightarrow$[/tex] They are 15 dollars.
- "It" changes to "They" for the plural form.
- "is" changes to "are" to agree with the plural subject "They."
Therefore, the conversation in plural form is:
1. Which ones
2. The red ones
3. They are 20 dollars
4. And the black ones?
5. They are 15 dollars.
This gives us:
```
Which ones
The red ones
They are 20 dollars
And the black ones?
They are 15 dollars.
```
