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.

y=5x+42

Where y is the money he earns and x is the number of person he serves.

Step-by-step explanation:

Let the number of person he serves =x

It is given that he earns $5 as tip for each person he serves.

Hence total tip earned for serving x person=5x

His fixed wages are $7 per hour and he works for 6 hours a day. Hence his wages per day are $7*6 =$42

Hence total money earned for a day , say y can be represented as

y=5x+42

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
