Answer:
No of clothes to be sold to gain $6000=20,000
Given:
Base salary = $4000
Rate of Commission = 10%
Amount salesman wants to earn in May = $6000
To find:
How much clothing units needed to be sold in order gain $6000 in may
<u>Step by Step Explanation:
</u>
Solution;
According to the formula;

=6000 - 4000 = 2000
Also we know,

Let the commission amount be x




x=20,000
Result:
Hence, the clothing to be sold in order to earn $6000 is 20,000 units.
Answer:
The result is
x + b/2a= ±√[(b² - 4ac)/2a]
Step-by-step explanation:
In the derivation of the quadratic formula by completing the square, the equation is created by forming a perfect square trinomial
ax² + bx + c = 0
x² + (b/a)x + c/a = 0
x² + 2(b/2a)x + b²/4a² - b²/4a² + c/a = 0
(x + b/2a)² - b²/4a² + c/a = 0
(x + b/2a)² = b²/4a² - c/a
(x + b/2a)² = (b² - 4ac)/2a
Apply square roots to both sides
x + b/2a= ±√[(b² - 4ac)/2a]
