Sam is a waiter at a local restaurant where he earns wages of $6 per hour. Sam figures that he also earns about $2.50 in tips for each person he serves. Sam works 4 hours on a particular day. If n represents the number of people Sam serves that day, which of the following functions could Sam use to figure E, his total earnings for the day?

A. E(n) = 2.5n
B. E(n) = 4n + 10
C. E(n) = 2.5n + 24

Answer 1

C.

24 means that you earned 6 dollars an hour for 4 hours. 2.5n means that for every person, n, you receive an additional $2.50.

Answer 2

Answer: C)
`E=2.5n+24`

Explanation:

Given: The rate of amount Sam earns each hour =$6

The number of hours he works on a particular day =4

Then , the amount earned by Sam excluding tips =
`4*6=\$24`

Amount he earned as tip by each person he serves =$2.50

If n represents the number of people Sam serves that day, then the amount he earns from tip in a day = 2.5n

Now, the function used by Sam to figure E, his total earnings for the day is given by :-

`E=2.5n+24`
