Answer 1

The waitress starts with RM20 in her tip jar at noon and makes RM0.50 per additional customer. To calculate the total in her tip jar after serving n more customers, you multiply RM0.50 by n and add the result to RM20.

Step-by-step explanation:

The subject of this question is Mathematics, specifically related to linear equations and arithmetic operations. This is a common problem-solving scenario for middle school students, where they are required to apply basic algebraic concepts to a real-world situation involving money and tips.

Step-by-Step Solution

At noon, the waitress notices she has RM20 in her tip jar. For each additional customer she serves, she makes an average of RM0.50. To find out how much she will have in her tip jar after serving n more customers during her shift, we use the formula:

T = C + (n × P)

• T represents the total amount in the tip jar after serving n customers.
• C is the current amount in the tip jar, which is RM20.
• n is the number of additional customers served.
• P is the average tip per customer, which is RM0.50.

Substituting the values we have:

T = RM20 + (n × RM0.50)

The waitress will have RM20 plus 50 cents for each additional customer she serves in her tip jar after her shift.
