Answer:
3610 dollars
Step-by-step explanation:
Remark
If you take the Cube Root of the volume, that will give you the length of an edge of the cube. If you square the edge, you get the area of one of the faces of the cube.
The Cost = the Area of 1 face * 10 dollars. is the answer.
Given
Volume = 6859 cubic feet
Cost per square foot = 10 dollars.
Solution
V = 6859 feet^3 Take the cube root of both sides
Edge = ∛V
Edge = ∛V = ∛6859
Edge = 19 feet exactly.
Area of the floor = s^2
Area of the floor = 19^2
Area of the floor = 361 square feet
Cost = 10 * 361 = $3610
2x² - 3x - 20
40
2 20
4 10
5 8
2x² - 8x 5x - 20
2x(x - 4) 5(x - 4)
(2x + 5) (x - 4)
2x + 5 = 0 x - 4 = 0
2x = -5 x = 4
x = -5/2
C) x = -2.5 and 4

Answer:
8710 units
Step-by-step explanation:
<em>Step 1: Write all the data</em>
Fixed cost: $9000
Average variable cost: 9.3 per unit
Total cost: 90,000
Total units: x
<em>Step 2: Find the total variable cost</em>
Average variable cost is per unit so it has to be multiplied by the number of units to find the total variable cost.
Total variable cost = average variable cost per unit x number of units
Total variable cost = 9.3x
<em>Step 3: Make the formula for finding x</em>
Total cost = total fixed cost + total variable cost
90,000 = 9000 + 9.3x
81000 = 9.3x
x = 8709.67
Rounded off to 8710 units
