Answer:
the depreciation expense increased by 50% during the current year.
Explanation:
Current Year Prior Year % change
Sales $120,000 $100,000 +20%
Cost of Goods Sold $80,000 $60,000 +33.33%
Depreciation Expense $30,000 $20,000 +50%
Interest Expense $2,000 $5,000 -60%
Even though the interest expense changed in a higher percentage (-60%), the question asked for which item increased the most, but the interest expense decreased.
Answer:
Reach
Explanation:
Marketing reach is a metric used by sellers to estimate the portion of the target market that have been exposed to their adverts.
This is an important metric that shows how effective marketing efforts are, it also indicates wether more effort should be put into advertising to increase the reach.
Reach is calculated by dividing impressions by frequency.
Impression is the total number of times an advert is displayed while frequency is the number of times it is viewed.
Answer:
D
Explanation:
A price floor is when the government or an agency of the government sets the minimum price of a product. A price floor is binding if it is set above equilibrium price.
A price floor increases producer surplus and reduces consumer surplus
Consumer surplus is the difference between the willingness to pay of a consumer and the price of the good.
Consumer surplus = willingness to pay – price of the good
Producer surplus is the difference between the price of a good and the least price the seller is willing to sell the product
Producer surplus = price – least price the seller is willing to accept
The dead weight loss of tax can be determined by calculating the reduction in total surplus as a result of the tax
Given Information:
Vdc = VF-L = 2.18x10⁶ V = 2,180,000 V
VF-L = voltage at full load
Ripple factor = r = 0.1 %
Voltage Regulation = VR = 0.05 %
Required Information:
Ripple voltage = Vr = ?
No-Load Voltage = VN-L = ?
Answer:
a. Ripple voltage = Vr = 2,180 V
b. No-Load Voltage = VN-L = 2,181,090 V
Solution:
a. Ripple Voltage Vr
The ripple factor is a measure of effectiveness of the rectification (the conversion of AC to DC) and it should be as low as possible.
The ripple factor is given by
r = Vr/Vdc
Re-arranging the formula to find ripple voltage Vr
Vr = Vdc*r
Vr = (2.18x10⁶)*0.001
Vr = 2,180 V
b. No-Load Voltage VN-L
Voltage regulation is given by
VR = (VN-L - VF-L)/VF-L
Re-arranging the formula to find the no-load voltage VN-L
VN-L = VR*VF-L + VF-L
VN-L = 0.0005*2.18x10⁶ + 2.18x10⁶
VN-L = 1090 + 2.18x10⁶
VN-L = 2,181,090 V
VN-L = 2.181x10⁶ V
