To find the discounted price, you need to calculate 20% of the original price and subtract that from the original price.

Here’s the process:

1. Original price = 180 pesos
2. Discount = 20% of 180 pesos
   $\text{Discount} = 180 \times 0.20 = 36 \text{ pesos}$
3. Discounted price = Original price - Discount
   $\text{Discounted price} = 180 - 36 = 144 \text{ pesos}$

So, the discounted price is 144 pesos.
