The problem you've shared from the image is a system of linear equations involving parking rates for motorbikes and cars. Let's break it down.

### Given Information:
1. There are 45 vehicles in total, consisting of motorbikes and cars.
2. The parking rate is:
   - Rp2,000 for motorbikes.
   - Rp3,000 for cars.
3. The total amount collected is Rp105,000.

We can define two variables:
- Let \( x \) be the number of motorbikes.
- Let \( y \) be the number of cars.

### Equations:
1. The total number of vehicles:
   \[
   x + y = 45
   \]
2. The total parking revenue:
   \[
   2000x + 3000y = 105000
   \]

### Solving the System of Equations:
Now, I'll solve these two equations to find the number of motorbikes \( x \) and cars \( y \).The solution to the system of equations gives:
- \( x = 30 \) motorbikes.
- \( y = 15 \) cars.

Thus, there are 30 motorbikes and 15 cars in the parking lot.

Do you want further explanation on how this was solved or any other questions?

Here are five related questions for further exploration:
1. What would happen if the total revenue was Rp120,000? How would that affect the number of motorbikes and cars?
2. Can you solve a similar problem where the parking rates are different for different vehicle types?
3. How would the solution change if there were a discount for parking cars for more than 2 hours?
4. Can you write the general formula for solving problems like this with different vehicle totals and parking rates?
5. How would the solution change if the parking lot had a maximum capacity for cars or motorbikes?

**Tip:** In word problems involving total counts and totals of different values, setting up a system of linear equations is the key to finding the solution!

Pada sebuah tempat parkir terdapat 45 kendaraan yang terdiri atas sepeda motor dan mobil. Tarif parkir flat untuk sepeda motor Rp2.000,00, sedangkan untuk mobil Rp3.000,00. Jika total uang yang diterima penjaga parkir saat itu Rp105.000,00, dapatkah kalian menentukan masing-masing jumlah sepeda motor dan mobil di tempat parkir tersebut? Bagaimana caranya?

This problem involves solving a system of linear equations to determine the number of motorbikes and cars parked. The total number of vehicles is 45, with a total revenue of Rp105.000. Learn how to break down and solve this word problem using algebraic methods.
