KAYAK Corporation makes a kayak with the following standard costs per unit produced: Actual Results: 11,000 units produced Direct material - Actually purchased and used 35,000 lbs for a total cost of $131,250. Direct Labor - Actually worked 14,000 hours at an e,erage labor rate of $20.25/hr. Variable Overhead Cost - Actual variable overtead costs were $42,000 allocated on dil hours Required: a. Compute total production costs, standard and actual, and calculate total production cos b. Compute the total materials cost variance and determine how much is driven by quant and how much by price variance. c. Compute the total labor cost variance and determine how is driven by efficiency variar much by rate variance. d. Compute the total overhead cost variance and determine how much is driven by over efficiency variance and how much by rate variance
