$$Original BudgetFlexed BudgetActualBudget VarianceDirect labor$ $2400$$ $2378$

The original budget is based on the expectation that $4,000$ books would be bound; the standard is $25$ books per hour at a pay rate of $$15$ per hour. During the week, $3,800$ books were actually bound. Employees worked $164$ hours at an actual total cost of $$2,378.$

Required:

Calculate the flexed budget amount against which actual performance should be evaluated and then calculate the budget variance.

Calculate the direct labor efficiency variance in terms of hours.

Calculate the direct labor rate variance.
