The number of rolls of toilet paper a person uses per year can vary depending on several factors, but here's a general idea:
Average: Estimates suggest the average person uses around 85 rolls of toilet paper per year, based on rolls with 150 sheets each. This translates to roughly 13,000 sheets annually.
So it means that I would spend 85*10 pesos
850 pesos a year minimum
it is not too much , but it will help me save money and at the same time, taking care for the environment
