At the beginning of the year, Crane Company had budgeted $30,600 for its variable-MOH costs, based on budgeted production of 510 units. Since the company had recently made significant investments in processing automation, it used machine hours to allocate MOH costs. Each unit was expected to use 5 machine hours of processing time. By the end of the year, Crane had used 2,500 machine hours and had accumulated total variable-MOH costs of $33,250 to process 550 units. Calculate Crane's variable-MOH price and efficiency variances.
