Answer:

Allocated overhead= $1,430,600

Explanation:

Giving the following information:

The company's executives estimated that direct labor would be $3,750,000 (250,000 hours at $15/hour) and that factory overhead would be $1,550,000 for the current period.

The records show that there had been 230,000 hours of direct labor.

Using direct labor hours as a base.

Predetermined overhead rate= total estimated manfacturing overhead for the period/ total amount of allocation base

Predetermined overhead rate= 1555000/250000= $6.22 per hour

Allocated overhead= Predetermined overhead rate*actual hours= 6.22* 230000= $1,430,600

Which of the following are arguments that are given to support trade barriers?
Roman55 [17]

Answer:

E To prevent dumping

Explanation:

There are several arguments that are given to support trade barriers; one of which is to prevent dumping. A country would place embargo on imports with respect to some of the goods that are produced in her country. This is to enable and encourage local production of such goods. Where a country permits importation of goods that are produced locally, such action could being down the efforts of local production ; hence local industries might not thrive in terms of production.

Also, placing embargo on the importation of goods that are produced locally in a country would take away the possibility of making the country for dumping ground in terms of goods that are not up to standard, produced in a foreign country and same would have been imported.
