Answer: 8%
Explanation:
The Annual Percentage Rate or APR for short is calculated by dividing the finance cost by the total amount borrowed in the following manner,
APR = Finance Charge / Amount borrowed.
To calculate the Finance charge we add the interest and the service charge.
Finance charge = 25 + 15
= $40
Back to the APR formula we will have,
APR = Finance Charge / Amount borrowed
APR = 40/500
= 0.08
APR is 8%.
Answer:
The delivery cycle time was 26.9
Explanation:
The delivery cycle time is computed as:
Delivery cycle time = Wait time + Throughput time
where
Wait time is 13.6
The formula for computing the throughput time is as:
Throughput time = Move time + Process time + Queue time + Inspection time
where
Move time is 3.3
Process time is 2.7
Queue time is 7.0
Inspection time is 0.3
Putting values above:
Throughput time = 3.3 + 2.7 + 7.0 + 0.3
Throughput time = 13.3
Now, putting both the values above:
Delivery cycle time = 13.6 + 13.3
Delivery cycle time = 26.9
Answer:
(B) $20 billion
Explanation:
Given a certain level of MPC, an increase in government spending (G) by a certain amount translates to an increase in aggregate demand (AD) through the relationship below.

where Δ means <em>change.</em>
<em />
Therefore, given ΔAD of $50 billion, and MPC of 0.6,

= 
= 
= ΔG = 50 * 0.4 = 20
Therefore, increase in government purchases = $20 billion.
Solution:
Annual coupon payment of the bond is $80
At the beginning of the year, remaining maturity period is 2 years.
Price of the bond is equal to face value, i.e. the initial price of the bond is $1000.
New price of the bond = present value of the final coupon payment + present value of the maturity amount.
New price of the bond = 
where, r is the yield to maturity at the end of the year.
Substitute 0.06 for r in the above equation,
Therefore new price of the bond is = 
= 
= $ 1010.87
Calculating the rate of return of the bond as


= 0.09887
Therefore, the rate of return on the bond is 9.887%
≈ 10 %
