Answer:
The profit per year will be $23916
Step-by-step explanation:
Cost price of 1 ft³ = $2.05
Selling price of 1 ft³ = $21.98
Profit = Selling price - cost price
profit = $21.98 - $2.05
Profit = $19.93
Profit on 1 ft³ is $19.93
If they sell 100 monthly, per year (12 months), profit will be
19.93*100*12
= $23916
The equation to model the above scenario is
+22x - 23 = 0
The perimeter of the expanded rectangle is 48 units
<h3>What is a rectangle?</h3>
A rectangle is a quadrilateral with its 4 angles 90°
Analysis:
First rectangle:
length = 10 + x
width = x
Second rectangle:
length = x + 14
width = x + 8
Area of expanded rectangle = 135 square unit
(x+8)(x+14) = 135
+ 8x + 14x + 112 = 135
+ 8x + 14x -23 = 0
+ 22x -23 = 0
+ 23x - x - 23 = 0
(x-1)(x+23) = 0
Therefore x = 1
Expanded length = 1+14 = 15
Expanded width = 1+8 = 9
Perimeter = 2(9+15) = 48 units
