The problem states that the price of a shirt and a pair of pants in a store is the same, denoted as \( p \) rupiah. The shirt receives a 20% discount, and the pants receive a 30% discount. We are tasked with finding the total price after both discounts.

Let's solve it step by step:

1. The original price of the shirt is \( p \). With a 20% discount, the new price of the shirt is:
   \[
   p - 0.20p = 0.80p
   \]
   This means the shirt now costs \( 80\% \) of the original price.

2. The original price of the pants is also \( p \). With a 30% discount, the new price of the pants is:
   \[
   p - 0.30p = 0.70p
   \]
   This means the pants now cost \( 70\% \) of the original price.

3. The total price for both the shirt and pants after discounts is the sum of the discounted prices:
   \[
   0.80p + 0.70p = 1.50p
   \]
   So, the total price becomes \( 1.50p \), or 150% of the original price of either the shirt or pants.

Thus, the total price of the shirt and pants after the discounts is \( 1.50p \).

Would you like any further clarification or details on this?

Here are some related questions:
1. What would the total price be if the shirt had a 10% discount and the pants had a 40% discount?
2. How much money is saved from the original price if the shirt's price is \( p = 100,000 \) rupiah?
3. If the price of both items doubled before discounts, how would the total after-discount price change?
4. Can you find a general formula if the shirt and pants have different original prices?
5. What happens to the total price if both items receive the same discount?

**Tip:** Always subtract the percentage discount from 100% to quickly determine the remaining cost of an item.
