Sam is a waiter at a local restaurant where he earns wages of $5 per hour. Sam figures that he also earns about $3 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) = 3n
b. E(n) = 3n + 30
c. E(n) = 5n + 18

Sam's total earnings, E(n) can be obtained by taking the sum of his base pay $30 (5 dollars per hour multiplied by 6 hours), and tips ($3 multiplied by each tip obtained n).

This can be shown in the equation below:

E(n) = 3n + 30

E(n) = 3n + 30 is the function could Sam use to figure E, his total earnings for the day. Option b is correct.

What is the equation?

A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.

Sam earns as wages = $5 per hour

Sam earns in tips = $3

No of hour sam works = 6 hours

n represents the number of people Sam serves that day,

E(n) = earn as tips × number of people sam serves that day, + no of hour × earn per hour

E(n) = 3n + 30

Hence, E(n) = 3n + 30 is the function could Sam use to figure E, his total earnings for the day.

Hence, option b is correct.
