Sam is a waiter at a local restaurant where he earns wages of $7per 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

There aren't any functions listed to choose from, but it should look something like the following:

E= total earnings that day
h= # hours worked that day
n= # people served that day

E= 7h + 5n

substitute 6 hours in for h

E= 7(6) + 5n

E= 42 + 5n OR E= 5n + 42

Hope this helps! :)
