Answer: C) [tex]E=2.5n+24[/tex]

Step-by-step 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 =[tex]4\times6=\$24[/tex]

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 :-

[tex]E=2.5n+24[/tex]
