Camelback Industries operates a delivery service for local restaurants, delivering call-in, to-go meals for restaurant customers. Variable overhead costs are applied at the budgeted rate of $16 per driving hour. The typical round trip takes a driver 15 minutes to complete. Actual results for March follow. Number of round trips run: 1,490 Hours of delivery time: 1,110 Variable overhead cost incurred: $3,800 Camelback uses flexible budgets and variance analysis to monitor performance. Required: A. Prepare a flexible-budget performance report that shows (1) actual variable overhead, (2) the amount of variable overhead that should have been incurred for the number of round trips taken, and (3) the variance between these amounts. B. Compute the company's variable-overhead spending and efficiency variances. (Indicate the effect of each variance by selecting "Favorable" or "Unfavorable". Select "None" and enter "0" for no effect (i.e., zero variance).)
