Answer:
6 hours
Explanation:
Let k = time it takes Karen to paint the house alone
then according to the question,
(2/3)(k)(1/k + 1/12) = 1
⇒(2k/3)(1/k + 1/12) = 1
⇒(2k)(1/k + 1/12) = 3
⇒(2 + k/6) = 3
Multiplying both sides by 6:
12 + k = 18
k = 6 hours
therefore Karen takes 6 hours to complete the Task.

Explanation:
Reserves is the total amount of a bank's deposit that is not given out as loans
Reserves = Deposits - outstanding loans
$100,000 - $70,000 = $30,000
Required reserves is the percentage of deposits required of banks to keep as reserves by the central bank
Required reserves = reserve requirement x deposits
0.2 x $100,000 = $20,000
Excess reserves is the difference between reserves and required reserves
$30,000 - $20,000 = $10,000

1. The payback period of the investment is:
= 5 years.
2. No. The payback period would not be affected if the cash inflow in the last year were several times as large. The payback period was reached in the 5th year, which is half-way before the last year. As it stands, no cash inflows after the 5th year will have any impact on the payback period.
Explanation:
a) Data and Calculations:
Cash flows:
Year Investment Cash Inflow Cumulative inflow
1 $ 42,000 $ 3,000 $3,000
2 5,000 $ 6,000 9,000
3 $ 12,000 21,000
4 $ 14,000 35,000
5 $ 16,000 51,000
6 $ 15,000
7 $ 13,000
8 $ 11,000
9 $ 10,000
10 $ 10,000
Total $47,000 $110,000
