Here's your shmoop du jour, brought to you by Traveling Salesmen.

00:07

If you turn out all the lights and hide under your bed, they won't even know you're home.

00:12

A salesman earns a base pay of $12/hour plus 5% commission on his sales.

00:17

If he sells $35,000 worth of goods working seven 8-hour days, how much is his total pay?

00:27

Okay, so we're trying to find the total income of a salesman.

00:31

His pay comes from two sources: Hourly rate, and commission.

00:36

The sum of the two is what we're looking for.

00:39

First, we'll find his hourly rate.

00:41

Well each hour, the salesman earns 12 bucks, but how long did he work?

00:46

Well, he worked seven 8 hour days,

00:49

so we can just get a total by multiplying the two and we get 7 times 8 is

00:53

56 hours total for that week.

00:55

Now we just multiply $12 per hour by 56 hours and that gets us $672 in a week,

01:02

but we can't forget his 5% commission on his $35,000 of sales.

01:06

We can multiply 35,000 by .05 to get $1,750.

01:13

From his hourly rate, the salesman earns $672, and another $1,750 from commission.

01:19

And it totals $2,422.

01:22

Not bad for a week's work.
