Question

At noon, a waitress notices she has rm20 in her tip jar. if she makes an average of rm0.50 from each customer, how much will she have in her tip jar if she serves n more customers during her shift

Answer 1

The waitress's total amount in the tip jar after serving n additional customers is calculated by adding RM20 to RM0.50 multiplied by n (RM20 + RM0.50 × n).

Step-by-step explanation:

The student is asking a mathematics question related to linear equations or arithmetic sequences in particular. The waitress currently has RM20 in her tip jar and earns an average of RM0.50 per customer served. If she serves n additional customers, the total amount in the tip jar will be the initial RM20 plus RM0.50 times the number of additional customers (n).

To calculate the total amount in the tip jar after serving n more customers, use the following steps:

1. Start with the initial amount in the tip jar, which is RM20.
2. Multiply the number of additional customers (n) by the average tip per customer, which is RM0.50.
3. Add this product to the initial RM20 to find the total amount in the tip jar.

The mathematical expression for this calculation is RM20 + (RM0.50 × n)
