LIFO method
Units Available for sale = 25 + 20 + 30 + 15 = 90 units
Ending Inventory = 24 units
Units Sold = (90 – 24) = 66 units
Cost of Goods Sold
Sales from September = 15 units x $45 = $675
Sales from June = 30 units x $38 = $1140
Sales from March = 20 units x $42 = $900
Sales from Beginning Inventory = 1 unit x $25 = $25
Total: 66 units = $2740
Ending Inventory from beginning inventory = 24 units x 35 = $840
Answer: 75-watt are 30$ fluorescent are 30$ in the second and 65$ in the first
Step-by-step explanation: i calculated thirty 75-watt and the fluorescent and got these kinda hard to explain hope i helped:)
The answer you are looking for could either be 16 or 40. To solve the equation, you would follow the steps of PEMDAS. Since the 2 above the equation is an exponent, you'd first solve there.
Fill in "a" and "b", the equation will now say 2^2 * 3 + 4 = ?. Assuming that the exponent is meant to go with the 2 alone, 2 * 2 = 4. This leaves the equation to say 4 * 3 + 4 = ? Multiply 3 and 4 to get 12, then add 4 to get 16.
OR
Fill in "a" and "b". This time, we're assuming that the exponent is going with 2 * 3 (originally 2a). Multiply 2 and 3 to get 6, then square 6 to get 36. Finally, add 4 to 36 to get 40.
I'm not quite sure where the exponent was meant to go, but I hope this helps!
Answer:
B) It decreases 22% per year.
Step-by-step explanation:
We are given that The value, v(.r), of his portfolio can be modeled with the function : 
Where x is the number of years since he made his investment.
Formula :
Where P = Principal
r = rate of decrease
t = time
A = Amount after t years
So, On comparing
P = 30000
t=x
A=y(x)
So, r = 0.22
r=22%
So, Rate of decrease is 22%
So, Option B is true,
It decreases 22% per year.
