The magnitude and the direction of the <em>resulting</em> vector is 3 and 0°, respectively.
<h3>Procedure - Determination of a vector by subtraction</h3>
Let assume that angles are in standard position. According to the statement, we have following model for the direction of the <em>resulting</em> vector in terms of the vectors known in statement:
(1)
Where is the resulting vector.
If we know that , and , then we have the following expression:
Then we have the following system of linear equations:
(2)
(3)
By (3):
By (2):
Hence, the magnitude and the direction of the <em>resulting</em> vector is 3 and 0°, respectively.

Answer:
$7.5 is the ROI on each sweatshirt
Step-by-step explanation:
In this question, we are asked to calculate ROI for a businessman who sells sweatshirts.
To calculate the profit we need to subtract the total cost incurred form manufacture to delivery and subtract bogus from the cost at which he sells the shirts.
Mathematically let’s calculate the cost from production to delivery.
That would be ;
$15 + $3 + $0.5 = $18.5
sales price is $26
His ROI will be $26 - $18.5 = $7.5
