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?

Answer 1

E = 42 + 5n

Explanation:

Answer 2

`7h+5n=E`

or

`42+5n=E`

Explanation:

First write an equation : note key words like "per", "each" and "total".

7 per hour

5 each

6 hours

n= number of people

E= total earnings

total earnings

So:

`7h+5n=E`

$7 per hour plus $5 tips per person equals total earnings

`7(6)+5n=E\\42+5n=E\\`
