The best pricing decision that is made is to sell each unit for $3.
<h3>How to calculate the price?</h3>
From the information given, the revenue will be:
= Customer × Charge
= 16 × 10
= 160
Based on the information given, the equation will be:
(10 + x)(16 - 2x) ≥ 130
160 - 20x + 16x - 2x² ≥ 130
-2x² - 4x + 30 ≥ 0
x² + 2x -15 ≤ 0
(x+1)² ≤ 4²
x+1 ≤ 4
x ≤ 3

Answer:
Trapezoid since it has one pair of parallel side and 4 sides.
X² - 8x = 9
x² - 8x - 9 = 0
x² + x - 9x - 9 = 0
x(x + 1) -9(x + 1) = 0
(x+1)(x-9) = 0
x = -1 or 9
In short, Your Answers would be -1 & 9
Hope this helps!
Answer:
It will take 3.6 hours to wax a car if they work together.
Step-by-step explanation:
Calvin one hour work = 
Alvin one hour work = 
To find out how much they can do together per hour,
We have to add and
= 
= 
--------------(1)
They can do of the job per hour.
If "t" is the time taken to finish the job together, then one hour work
------------------------(2)
Now we have to find the value of "t" by setting the expression (1) and (2) equal.
It can solve by flipping the equation;
t = 3.6 hours
It will take 3.6 hours to wax a car if they work together.
