Adams Manufacturing allocates overhead to production on the basis of direct labor costs. At the beginning of the year, Adams estimated total overhead of $396,000; materials of $410,000 and direct labor of $220,000. During the year Adams incurred $418,000 in materials costs, $413,200 in overhead costs and $224,000 in direct labor costs. Compute the predetermined overhead rate.

Answers

Answer:

1.8 times the cost of labor.

Step-by-step explanation:

At the beginning of the year, the rate for overhead was estimated to be ...

(overhead $)/(direct labor $) = $396/$220 = 1.8

The overhead rate is 1.8 times the labor cost.

1.25 = (d/32) + (d/48)

Answers

Answer:

d =24

Step-by-step explanation:

1.25=3d/96+2d/96

1.25=3d+2d/96

1.25=5d/96

96•1.25=96•5d/96

96•1.25=5d

120=5d

120/5=5d/5

d =24

If 10 people apply for 3 jobs in how many ways can people be chosen for the jobs. 1. If the jobs are all the same. 2. If the jobs are all different. (please, please show work! Thank you!)

Answers

Answer:

1. 120 ways

2. 720 ways

Step-by-step explanation:

When the order is important, we have a permutation.

When the order is not important, we have a combination.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_((n,x)) = (n!)/((n-x)!)$

Combinations formula:

$C_(n,x)$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_(n,x) = (n!)/(x!(n-x)!)$

1. If the jobs are all the same.

Same jobs means that the order is not important. So

3 from a set of 10.

$C_(10,3) = (10!)/(3!(10-3)!) = 120$

120 ways

2. If the jobs are all different.

DIfferent jobs means that the order matters.

$P_((10,3)) = (10!)/((10-3)!) = 720$

720 ways
