Answer:
Spending variance= $43 favorable
Explanation:
Giving the following information:
Standard:
Fixed costs= $210
Variable cost per job= $86
Variable cost per meal= $15
The actual activity was 28 jobs and 217 meals. The actual cost for catering supplies in March was $5,830.
To calculate the spending variance, we need to use the following formula:
Spending variance= (actual costs - standard costs)
Standard costs= 210 + 28*86 + 15*217= 5,873
Spending variance= 5,830 - 5,873
Spending variance= $43 favorable
Answer:
(a) Given that a chip passes the test, what is the probability that it is a good chip?
LetB = {the chip is good}
A={the chip passes the cheap test}.
Bc={the chip is bad}
Ac={the chip fails the cheap test}
P(A | B) = 1
P(A | B
c
) = 0.075
= 
= 
≈ 0.9751
(b) If the company sells all chips that pass the cheaper test, what percentage of sold chips will be bad?
P(B
c |A) = 1 − P(B | A) = 1 - 0.9751 = 0.0249

Answer:
The variable overhead rate variance for the month is $2,548 favorable
Explanation:
In this question, we use the formula of the variable overhead rate variance which is shown below:
= Actual level of activity × (Standard rate - Actual rate )
= 9,100 × ($7.60 - $7.32)
= 9,100 × 0.28
= $2,548 favorable
The actual rate is not given in the question, so we have to compute by using the formula which is given below:
= Actual total variable manufacturing overhead ÷ Actual level of activity
= $66,600 ÷ 9,100
= $7.32
Hence, the variable overhead rate variance for the month is $2,548 favorable
