So in this problem we can state that each T-shirt costs S19 each. And if Kate buys two she gets a 30% off with the second shirt she buys. <span>And how much will she pay?
Solution:</span> <span><span>
1. </span>19 for each t-shirt</span> <span><span>
2. </span>Total of $38 if not provided with 30% off</span>
<span><span>3. </span>19 x 0.3 = 5.7</span>
<span><span>4. </span>Hence 30% of $19 is $5.7</span>
<span><span>5. </span>Next is we deduct $5.7 which is 30% of $19.</span> <span><span>
6. </span>19 – 5.7 = $13.3</span> <span><span>
7. </span>Therefore we add one shirt for $19 and the second, less 30% off which now only costs for $13.3.</span> <span><span>
8. </span>19 + 13.3 = 32.3</span>
<span><span>9. </span>Conclusively, she will pay $32.3 for the shirts.</span>
Answer:
hence the required minimum production level is 12units
Step-by-step explanation:
Given the cost function expressed as c(x) = x^3 - 24x^2 + 30,000x
The average cost function will be c(x)/x
Dividing the cost function through by x
Average cost function = c(x)/x = x³/x - 24x²/x + 30,000x/x
Average cost function = x²-24x + 30,000
A(x) = x²-24x + 30,000
If the average cost is minimized, hence dA/dx = 0
dA/dx = 2x - 24
0 = 2x - 24
-2x = -24
Divide both sides by -2
-2x/-2 = -24/-2
x = 12
For the second deriviative
d²A/dx² = 2 which is greater than zero
Hence a production level that will minimize the average cost per item of making x items is 12
Answer is d just took the test
Answer:
Step-by-step explanation:
Comment
This is an arithmetic series. It has the following givens.
a = 27 The first term
d = - 2 The difference between one term and the one behind it.
n = quite small
Tn = a + (n - 1)*d
tn = 27 - 2n + 2
tn = 29 - 2n
Answer: b: s=n x 23
Step-by-step explanation:
When looking at the coordinates on the graph, each point increases by 23. 23 is multiplied by the number day it is (n)
