Answer:
The correct answer is (A)
Explanation:
Nike and Adidas are considered as substitute goods that means they have positive cross elasticity of demand. When the price of Nike soccer balls fell, Rolando purchased more Nike balls compared to Adidas balls because of the substitution effect. The substitution effect led to this decision. A substitute effect is a change in the purchase decision, due to an increase in the price of one substitute good.
Answer: The nominal money supply should set at 1,600.
Explanation:
Given that,
Money demand function: (M/P)d = 2,200 – 200r
r - Interest rate
Money supply (M) = 2,000
Price level (P) = 2
If the fed wants to set the interest rate at 7% then,
Money supply = money demand
= 
= 2,200 – 200r
P = 2 and r = 7%
= 2,200 – 200 × 7
M = 800 × 2
M = 1,600
The nominal money supply should set at 1,600.
Answer:
The explanation is below
Explanation:
A. Shutdown point is achieved when price equal AVC. when price lowers than the AVC, firm shutdown.
VC = q^2
AVC = q
So,
P = q is the shutdown point.
B. For profit maximizing level of output,
P = MR = MC
500 = 20 + 2q
q = 240 units
So, profit maximization level of output = 240 units
C. Firm level supply curve = MC curve above the shutdown point
Number of firms = 5
So,
Industry supply curve = 10*MC = 200+20Q
Industry supply curve = 200+20Q
It shows that MC curve above the shutdown point is supply curve.
Answer:
$86.87
Explanation:
Calculation for what would be the overall margin on the order
Price of cake $500.54
Less Costs:Size related ($183.06)
($1.13 per guest × 162 guests)
Less Complexity-related ($130.56)
($43.52 per tier × 3 tiers)
Less Order-related ($61.44)
($61.44 per order × 1 order)
Less Cost of purchased decorations for cake ($38.61)
Customer margin $86.87
Therefore would be the overall margin on the order is $86.87
