Answer 1

The total number of batteries that Emily buys can be expressed as:

8p + 30b

Here, 8p represents the total number of batteries in the packs that Emily buys, and 30b represents the total number of batteries in the boxes that Emily buys. By adding these two terms together, we can find the total number of batteries that Emily buys.
