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.
The cost per foot of redwood and of pine is $3.5 and $1.5 respectively.
<h3>How to solve simultaneous equation?</h3>
let
- cost of redwood = x
- cost of pine = y
50x + 70y = 280
100x + 60y = 440
Multiply (1) by 2
100x + 140y = 560
100x + 60y = 440
subtract to eliminate x
80y = 120
y = 120/80
y = $1.5
substitute y = 1.5 into (1)
50x + 70y = 280
50x + 70(1.5) = 280
50x + 105 = 280
50x = 280 - 105
50x = 175
x = 175 / 50
x = $3.5

Answer:
See below.
Step-by-step explanation:
You know a and c.
c=√a²+√b² = 18.79=√17²+√b²
18.79=17+√b²
-17 -17
1.79=√b²
1.79=b
