Answer:
b. $1,144 unfavourable.
Explanation:
The computation of the variable overhead efficiency variance is shown below:
= (Actual Hours - Standard Hours) × Standard rate per hour
=(1,700 - 8.1 × 200 units) × $14.30
= 80 × $14.30
= $1,144 unfavorable
hence, the variable overhead efficiency variance is $1,144 unfavorable
Therefore the option b is correct
To determine the 90th percentile of waiting times to the next shutdown, we use the formula
(10)* E[X] = 2.30258509*E[X] 2.30258*12500 = 28782.31 HOURSTherefore, the 90th percentile of waiting times to the next shutdown will be approximately 28782 hours
Bob has to own his land for 18 years if the price is increasing at the rate of 6% per year.
Given that land was bought by Bob for $16390, the price is increasing at the rate of 6%, price of land today is $46817.
We are required to find the time for which Bob need to own the land so that the price of the land is $46817 today.
Compounding means calculating amount on the principal and the amount added interest.
Rate of increasing the price of land be 6%.
Price when Bob bought the land=$16390.
Price of land today=$46817.
It is like compounding of interest and the sum is calculated as under:
S=P*
In the above equation P is theamount at beginning,r is rate of increasing and n is the number of years.
46817=16390
46817/16390=
=2.8564
=
(Approximately)
From both the sides we will get n=18.
Hence Bob has to own his land for 18 years if the price is increasing at the rate of 6% per year.
