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

How do I Solve 4y + 3 = 2y + 14 ???

Aloiza [94]

$4y+3=2y+14$
subtract 2y from both sides to get the y figures on the same side.
$2y+3=14$
Then subract 3 from both sides to get the number values on the other side.
$2y=11$
Divide by 2 to get y alone.
$y=\frac{11}{2}$
$y= 5.5$

Find the missing angle or side. Round to the nearest tenth.

babymother [125]

Answer:

$x = 19.4$

Step-by-step explanation:

For the 72-deg angle, 6 is the adjacent leg. x is the hypotenuse. The trig ratio that relates the adjacent leg to the hypotenuse is the cosine.

$\cos A = \dfrac{adj}{hyp}$

$\cos 72^\circ = \dfrac{6}{x}$

$x \cos 72^\circ = 6$

$x = \dfrac{6}{\cos 72^\circ}$

$x = 19.4$
