Answer:
Option D
Step-by-step explanation:
Cost of 4 shirts all together = $85
Model given in the picture attached will be,
x + x + x + x = 85
4x = 85
x = 21.25
Therefore, Option D will be the correct option.

Answer:

Step-by-step explanation:
The y- intercept is at (0, 6) ⇒ c = 6
The x- coordinate of the vertex is at the midpoint of the zeros, that is
m = 
= 
= - 2
Since the zeros are x = - 3 and x = - 1 then the factors are (x + 3), (x + 1) and
f(x) = a(x + 3)(x + 1) = a(x² + 4x + 3)
Comparing with f(x) = ax² + 8x + 6 ⇒ a = 2
Thus
f(x) = 2x² + 8x + 6
Substitute m = - 2 into the equation for value of n
n = 2(- 2)² + 8(- 2) + 6 = 8 - 16 + 6 = - 2
Hence
c = 6, m = - 2, a = 2, n = - 2
Answer:
10.44
Step-by-step explanation:
The weighted average cost per unit method seeks to get the cost of goods sold as an average of all cost of goods in the inventory as at the time of sales.
Part of its objective is to strike a balance between the (FIFO and LIFO) inventory valuation methods.
Beginning inventory ( Jan) = 10 units
Cost of beginning inventory per unit = $10
Total cost of beginning inventory = Cost * Number of units
In this case (10*$10) = $100
Additional purchase (Jan 5) = 8 units
Cost of additional purchase per unit = $11
Total cost of additional purchase = 8 * $11 = $88
Weighted average cost per unit at the time 11 units are sold on January 7 = Total cost of units at that time / number of units available at that time.
= ($100+ $88) / (10+8)
= 188/18
=10.44 (approximated to 2 decimal places)
I hope this helps make the concept clear.
