saveliy_v [14]

Answer:

Step-by-step explanation:

I don"t really know the answer but i might have and explanation to help. Hollow everyday circular objects appear differently than drawn two-dimensional circles. Objects like pipes and hoses have two different diameters. The outside diameter measures the distance of a straight line from one point on the outside of the object, through its center, and to an opposite point on the outside. The internal diameter measures the inside of the object. Calculating the internal diameter depends on the outside diameter and the thickness of the outer circle.

Worth 33 points each!!
gogolik [260]

Where <em>x </em>is the number of books sold, <em>i </em>is income, and <em>c </em>is cost:

<em>c = 4x + 3500 </em> ($4 per book plus the 3500 flat marketing fee)

<em>i = 15x </em>($15 per book)

You are looking for the point where these intersect: the intersection is where the income is equal to the cost, and at any point after that the income is greater than the cost. So, set the equations equal to each other:

<em>4x + 3500 = 15x     </em>

subtract 4x from both sides

<em>3500 = 11x</em>              

divide both sides by 11

<em>x = 318.181818</em>

So, you would have to sell a minimum of 319 books in order to make a profit.
