Answer:
<u>The correct answer is that the average speed of Usain Bolt in 2009 was 10.42 meters per second.</u>
Step-by-step explanation:
<u>1. Let's check the information given to resolve the question:
</u>
World Record time of Usain Bolt = 9 seconds 3/5
Distance = 100 meters
Find his average speed in meters per second
<u>2. Let's find the average speed of Usain Bolt in 2009:</u>
World Record time of Usain Bolt = 9 seconds 3/5 = 9.6 seconds (3/5 = 0.6)
World Record time of Usain Bolt = Distance / World Record time
World Record time of Usain Bolt = 100 meters /9.6 seconds
World Record time of Usain Bolt = 10.416666 meters per second
World Record time of Usain Bolt = 10.42 meters per second (Rounding to two decimal places)
<u>The correct answer is that the average speed of Usain Bolt in 2009 was 10.42 meters per second.</u>
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.
