Problem 9-20 (Algo) Basic Variance Analysis; the Impact of Variances on Unit Costs [LO9-4, LO9-5, LO9. 6] Koontz Company manufactures a number of products. The standards relating to one of these products are shown below, along with actual cost data for May. The production superintendent was pleased when he saw this report and commented: "This $073 excess cost is well within the 4 percent limit management has set for acceptable variances. It's obvious that there's not much to worry about with this product" Actual production for the month was 18,000 units. Variable overhead cost is assigned to products on the basis of direct labor-hours. There were no beginning or ending inventories of materials. Required: 1. Compute the following variances for May? a. Materials pice and quantify variances b Labor rate and efficiency variances c. Variable overhead rate and efficiency variances. 2. How much of the 5073 excess unit cost is traceable to each of the varances computed in (1) above 3. How much of the $073 excess unit cost is traceable to apparent inefficient use of labor time? Complete this question by entering your answers in the tabs below. Complete this question by entering your answers in the tabs below. 1a. Compute the following variances for May, materials price and quantity variances. 1b. Compute the following variances for May, labor rate and efficiency variances. 1c. Compute the following variances for May, variable overhead rate and efficiency variances. (Indicate the effect of each variance by selecting "E" for favorable, "U" for unfavorable, and "None" for no effect (l.e., zero variance). Input all amounts as positive values.) 3. How much of the $0.73 excess unit cost is traceable to apparent inefficient use of labor time? Complete this question by entering your answers in the tabs below. How much of the $0.73 excess unit cost is traceable to each of the variances computed in (1) above. (Iridicate the effect of each variance by selecting " F " for favorable, " U " for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values. Round your answers to 2 decimal places.) Required: 1. Compute the following variances for May. a. Materials price and quantity variances. b. Labor rate and efficiency variances. c. Variable overhead rate and efficiency variances. 2. How much of the $073 excess unit cost is traceable to each of the variances computed in (1) above. 3. How much of the $073 excess unit cost is traceable to apparent ineficient use of labor time? Complete this question by entering your answers in the tabs below. How much of the 50.73 excess unit cost is traceable to apparent inefficient use of labor time? (Indicate the effect of each variance by selecting " F for favorable, " U " for unfavorable, and "None" for no offect (i.e, zero variance), Input all amounts as positive values. Do not round istermediate calculationn. Round your final anowern to 2 decimal places.)
