Based on expected production of 200,000 units, factory overhead costs budgeted for the year were: Variable costs $180,000 $0.90 per unit Total fixed costs $70,000 $0.35 per unit Actual production achieved was 180,000 units. Overhead costs incurred were: Variable costs $160,200 $0.89 per unit Total fixed costs $72,000 $0.40 per unit Required: The predetermined overhead recovery rate per unit The amount of over/under-applied overhead analysed into a spending (budget) variance and a capacity (volume) variance. Favourable (F) or Unfavourable (U) should be included in your variance calculation. Show all the workings in your answers.
