Question

Sam is a waiter at a local restaurant where he earns wages of $7 per hour. Sam figures that he also earns about $5 in tips for each person he serves. Sam works 6 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)=5n
B. E(n)=7n+30
C. E(n)=5n+42

Answer 1

C. E(n)=5n+42

5 times the number of people + 7 times 6

Answer 2

C. E(n)=5n+42

Here, n = number of people
& 6 * 7 = 42 [ wage without tip ]

Hope this helps!
