Rashawn recently spent $100 to open a store selling tee-shirts. At his business, he purchases plain tee-shirts for $11 each, pri
nts graphics on them, and then sells them for $26 each. What is the minimum number of tee-shirts that Rashawn would need to sell in order to make a profit of at least $400?
To answer this question you can write an equation that represents this situation.
I would subtract $11 (the cost per shirt) from the selling price to get $15 profit for each shirt. He paid $100 already and wants to profit $400, so the amount he needs to make is $500.
$15x = $500 would be the equation needed to answer this. x stands for the number of shirts.
Divide both sides by $15 to get x = 33.33.... shirts.
He would need to sell at least 34 to make at least $400 profit.
<em><u> It begins to move toward the right</u></em>
Explanation:
The given information can be summarized in this way:
First force vector: Fg = - 8N (vertical down)
Second force vector: Ft = 6N (horizonal right)
Third force vector: FN = 8N (vertical up)
Fourth vector: Ff = - 4N (horizontal left)
Following Newton's second law, net force equal mass times acceleration:
Net force = mass × acceleration
To predict the motion, you apply Newton's second law in each direction (vertical and horizontal)
<u>Vertical force balance:</u>
Net vertical force = 8N - 8N = 0. This means there is not motion in the vertical direction.
<u>Horizontal force balance:</u>
Net horizontal force = 6N - 4N = 2N. This means there is a net force of 2N to the right, which lets you predict that the bone starts to accelerate to the right; this is, the bone begins to move toward the right.
