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

From the secon equation, we can find x in terms of y by doing:
x = 2 + y
Pluggin this value of x in the first equation:
2(2 + y) - 2y = 14
4 = 14
We reached a false statement, which means that the given system of equations has no solutions. Another way to verify that would be by dividing the first equation by 2. Doing so, we would have equation 1: x - y = 7 and equation 2: x - y = 2, which is clearly impossible!
Answer: 11/10 or 1 1/10 pages
Step-by-step explanation:
3/5 + 1/2 = x
find the LCD so that you can add the fractions.
3/5 (2/2) = 6/10
1/2 (5/5) 5/10
6/10 + 5/10 = 11/10 or 1 1/10
