You own an accessories store, and sales last month were $24,000. You had $3,500 in discounts and $975 in returns.
Len [333]

Answer:

The net sales for last month were <u>$19,525</u>.

Step-by-step explanation:

Given:

Last month sales were $24,000.

Discounts is $3,500 and $975 in returns.

Now, to get the net sales for last month.

So, we deduct the discount:

<em>Sales - discounts</em> = \$24,000 - \$3,500 =\$20,500.

Then, we deduct the returns from the remaining amount:

<em>Sales after discounts - returns</em> = \$20,500 - \$975

                                                   = \$19,525.

Therefore, the net sales for last month were $19,525.

Can a pentagon have angles that measure 95°, 67°, 105°, 95°, and 177°?
pochemuha

Answer:

No, it cannot have angles that measure 95°, 67°, 105°, 95°, and 177°.

Step-by-step explanation:

S = (n-2) * 180

A pentagon has 5 sides, so substitute n for sides (n = 5)

s = 5-2) * 180 = 540°

95° +  67° + 105° + 95° + 177° = 539°

Hope that Helps!
