Answer:

The best unit price is Brand A.

Step-by-step explanation:

We can find the cost for each roll of toilet paper. For Brand A, we can do 49/7, which we get 7. That means that every roll of toilet paper cost $7 for Brand A. For Brand B, we do 72/9 and get 8. That means every roll of toilet paper cost $8 for Brand B. Since Brand A is cheaper per roll, Ariana should buy from that brand.
