Step-by-step explanation:
Given the following data;

![Cost = \frac {Amount \; paid}{Amount \; of \; pad}](https://img.qammunity.org/2022/formulas/chemistry/high-school/geewkpwrosaehwi1jdj69eeuxk67f19eyu.png)
Substituting into the formula, we have;
![Cost = \frac {180}{15}](https://img.qammunity.org/2022/formulas/chemistry/high-school/xvqw7j72o4xtmivvt1ylaghtzp5rbm20nk.png)
Cost = 12 pesos
Therefore, the cost of each pad bought by Lorena is 12 pesos.
