Question

At noon, a barista notices that she has $ 10 in her tip jar. If she makes an average of $ 0.50 from each customer, how much will she have in her tip jar if she serves n more customers during her shift

Answer 1

Answer:

Total Amount in Barista's tip jar = $ 10 + $ 0.50n

Step-by-step explanation:

Barista makes an average of $ 0.50 from each customer

So, for n more customers, She will be having following amount in her tip jar:

Additional tip amount = $ 0.50 x n

Here the word "additional" is used, because she already had an amount of $ 10 in her tip jar.

Adding this amount to her additional tip amount, we will get following expression:

Total Amount in Barista's tip jar = $ 10 + ($ 0.50 x n)
