Let's extract the information from the image and solve the problem:

**Question:**

- Harga satu unit laptop sama dengan 3 kali harga satu handphone.
- Harga 2 unit laptop dan 4 buah handphone adalah Rp 30.000.000,00.
  
Berapa uang yang harus dibayar Fahri untuk membeli 3 unit laptop dan 3 buah handphone?

---

Let’s define the unknowns:

- Let \( x \) be the price of one handphone.
- Then, the price of one laptop is \( 3x \) (since it's 3 times the price of one handphone).

From the problem:
- The total price of 2 laptops and 4 handphones is \( 30,000,000 \). Using our variables, this can be written as:
  \[
  2(3x) + 4x = 30,000,000
  \]
  Simplifying:
  \[
  6x + 4x = 30,000,000
  \]
  \[
  10x = 30,000,000
  \]
  \[
  x = 3,000,000
  \]
  So, the price of one handphone is Rp 3,000,000, and the price of one laptop is \( 3 \times 3,000,000 = 9,000,000 \).

Now, Fahri wants to buy 3 laptops and 3 handphones. The total cost will be:
\[
3(9,000,000) + 3(3,000,000) = 27,000,000 + 9,000,000 = 36,000,000
\]

So, Fahri has to pay **Rp 36,000,000**.

Here are 5 related questions for further practice:

1. What would be the total cost if Fahri wanted to buy 4 laptops and 5 handphones?
2. If the price of each handphone increased by 10%, how much would 2 laptops and 3 handphones cost?
3. What would the total cost be if Fahri got a discount of 15% on the price of the laptops?
4. How many handphones could Fahri buy with Rp 50,000,000 if he doesn't buy any laptops?
5. If another brand offers laptops that cost 2.5 times the price of a handphone, what would be the price difference compared to the original laptop?

**Tip:** When solving word problems, clearly define your variables and write down equations based on the relationships given in the problem. This helps to simplify and solve the problem step by step.
