True or false: The variable overhead rate variance uses the same basic formula as the labor rate variance except that the variab
Zanzabum

Answer:

True

Step-by-step explanation:

The variable overhead rate variance refers to the difference in two variables.

The Variables are

1. The actual variable manufacturing overhead

2. The expected variable overhead given the number of hours worked

Labor rate variance is evaluated by

AH(AR - SR)

AH = actual hours

AR = actual rate

SR = standard rate.

The variable overhead rate variance is also calculated the same way except that it replaces the direct labor rates with variable overhead rates

The Astronomical Telescope shop plans to introduce a new model based on the following information: Rent and utilities per period
dimaraw [331]

Using the profit concept, it is found that the break-even point is of 61.6 units.

  • Profit is given by revenue subtracted by cost.
  • The break-even point is when the revenue is the same as the cost, which means that the profit is zero.

In this problem:

  • Variable cost per unit x of $217, fixed cost of $5,420, thus, the cost equation is given by:

C(x) = 217x + 5420

Selling price per unit of $305, thus, the revenue equation is given by:

R(x) = 305x

The break-even point is the <u>value of x</u> for which:

R(x) = C(x)

Then

305x = 217x + 5420

88x = 5420

x = \frac{5420}{88}

x = 61.6

The break-even point is of 61.6 units.
