Answer: 8,000,000
Step-by-step explanation:
Given the following :
EOQ = 4000
Ordering cost (S) = $25
Carrying cost = 25% of unit cost
Cost per load = $100
Let annual demand = D
EOQ = sqrt[ ( 2 * S * D) / H]
Holding cost = H = 0.25 × $100 = $25
Hence,
4000 = sqrt[ ( 2 * 25 * D) / 25]
4000 = (50D /25)^1/2
Square both sides
4000² = 50D / 25
16,000,000 × 25 = 50D
400000000 = 50D
D = 400000000 / 50
D = 8,000,000
Hence, annual demand = 8,000,000
Direct variation is when
is the same for each coordinate.
Indirect variation is when x · y is the same for each coordinate.

The answer would be:
The x-intercept of the boundary line is (-3/2, 0).
The area below the line is shaded.
The slope of the line should be 2/3. The area below the line shaded because the function using y<.....
Coordinate 2,3 doesn't fulfill the function.
y < 2/3x + 1
3 < 2/3(2)+1
3< 4/3+1
3< 2.3 ---->false
X intercept is when the y variable is zero. If you put it to the equation
y = 2/3x + 1
0= 2/3x+1
2/3x= -1
x= -3/2
Answer:
$84.58
Step-by-step explanation:
You would do 9.95 times 8.5 which gives you 84.575 which in money case you round to two decimal places you keep the 5 but 7 you round to 8 because "5 or more you add one more"
Hope this helps
