Math Problem Statement

Nyatakan daftar harga di atas dalam bentuk matriks! (State the price list in matrix form!)

Solution

The task in the image asks to express the price list in matrix form based on the table provided. The table is a price list for different types of chocolate ("Cokelat batang," "Cokelat bulat," and "Wafer") for various quantities (Isi 10, 15, and 20).

Let's represent this price list as a matrix. The matrix will have rows representing the chocolate types and columns representing the quantities.

Here's the table:

JenisIsi 10Isi 15Isi 20
Cokelat batangRp35.000Rp45.000Rp55.000
Cokelat bulatRp28.000Rp42.000Rp50.000
WaferRp21.000Rp35.000Rp40.000

We can express this as a matrix AA:

35.000 & 45.000 & 55.000 \\ 28.000 & 42.000 & 50.000 \\ 21.000 & 35.000 & 40.000 \end{pmatrix}$$ This matrix $$A$$ represents the prices of the chocolate types for quantities 10, 15, and 20. Would you like further details or explanations? Here are 5 related questions you might find helpful: 1. How do you determine the size of a matrix from a table? 2. How can you perform matrix operations (addition, subtraction) with this price list? 3. What are the real-world applications of expressing data like this in matrix form? 4. How could this matrix be used to calculate total costs for different chocolate combinations? 5. What is matrix multiplication, and how would it apply to such a pricing table? **Tip:** Matrices are especially useful in representing data tables, making calculations and transformations easier!
