3/8 = 0,375
0,375 * 100% = 37,5 %
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.
X is your per hour y is the answer itself
Don’t Flush is y= 10x + 50
Fire hole is y= 5x + 90
Answer:
Part A: The outlier is the 60 lbs dogs, because this dog disrupts the common pattern amongst the others, therefore it is an outlier.
Part B: The mean of all 4 dogs is is 28.5, and the mean of the 3 dogs without an outlier is 13.5. This means the difference is 15, hence 28.5-13.5=15
