Answer:

Step-by-step explanation:

First, the profit formula:

PROFIT= TOTAL REVENUE - TOTAL COST

Next, note the points:

- Without Advertisement, Q = 6,000 where Q is quantity supplied

- A formula that gives the total profit P in dollars must take into account that 100cents = 1dollar

- Here, only a dollar is spent on advertisement, hence, Q = 6005

- Advertising expenses have been accounted for and [P = 9cents × Q] where Q is quantity sold.

- 9 cents = 0.09 dollars

TOTAL PROFIT FORMULA = 0.09Q - 500

Scilla [17]

Answer:

x = 4

3 x -7 = -21

12x -21 = 27

ArbitrLikvidat [17]

Answer:

This is the complete question;

What is the circumference of the circle?  shown in the image

(use 3.14 for pi )

A 18.84.98 cm

B. 36 cm

C. 37.68 cm

D. 37.7 cm

<em>The circumference of the circle would be "C" 37.68 cm</em>

Step-by-step explanation:

The circumference of a circle is the distance around or right around the circle. The circumference of the circle is also the perimeter of the circle.

<h3>Calculating the Circumference of the Circle.</h3>

The circumference of the circle can be obtained using the relationship below;

C = πd

Where C is the circumference and its unknown

d is the diameter of the circle = 12 cm

π is a constant = 3.14

C = 3.14 x 12

C = 37.68 cm

Therefore the circumference of the circle would be 37.68 cm
