A salesperson is paid an 8.25% commission on sales when the invoice is
son4ous [18]

Answer:

<em>The salesperson's commission for this month is $3,803</em>

Step-by-step explanation:

<u>Percentages</u>

Let's call x to the sales volume, not including commission.

The salesperson is paid an 8.25% commission on sales, thus the total invoice is x + 8.25%x = x + 0.0825x = 1.0825x

We are given this total invoice, thus:

1.0825x = $49,900

Dividing by 1.0825:

x = $46,097

The salesperson's commission is

0.0825*$46,097=$3,803

The salesperson's commission for this month is $3,803

The two lines with arrows are parallel, which means angles A and B are supplementary.

So we have

A + B = 180º

(6<em>x</em> - 35)º + (3<em>x</em> + 53)º = 180º

(9<em>x</em> + 18)º = 180º

(9<em>x</em>)º = 162º

<em>x</em> = 18

This means angle A has measure

A = (6<em>x</em> - 35)º = 73º
