Jawapan / Answer:

Identify Variables: question_prompt: How much does a packet of rice and a bottle of cooking oil cost if two sets of package $B$ cost $RM244.20$ using the matrix method?
Set Up Equations: Step $1$ : Let's denote the price of a packet of rice as $R$ and the price of a bottle of cooking oil as $C$ . We need to set up two equations based on the information given in the problem.
Use Matrix Method: Step $2$ : Since the customer buys two sets of package B, we can write the equation as $2R + 2C = 244.20$ . But we need another equation to solve for $R$ and $C$ using matrices, which we don't have yet.
