Answer:
Onaje is correct.
Step-by-step explanation:
To start, total up how many shirts we have, and multiply them by <em>t</em>. Since they are the same price, we now have a total for how many shirts they bought. This proves the second and third equations that they wrote. If you take the easy way and just add them, you'll still have 25<em>t</em>, making Onaje's expression correct.
EDIT: Just saw you need why it's incorrect for Paula, just hold on.
So for Paula, it's simple why she is incorrect. If you look at the third equation she wrote, she's adding 25 to 2t, which is completely incorrect, and will come up with a different result than 16t + 9t.
Hope this helps.
