NEED HELP! WHAT ARE THE MISTAKES IN THESE PROBLEMS

Exercise 10-1 (Algo) Direct Materials Variances [LO10-1] Bandar Industries manufactures sporting equipment. One of the company's products is a football helmet that requires special plastic. During the quarter ending June 30 , the company manufactured 3,900 helmets, using 2,964 kilograms of plastic. The plastic cost the company $22,526. According to the standard cost card, each helmet should require 0.67 kilogram of plastic, at a cost of $8.00 per kilogram. Required: 1. What is the standard quantity of kilograms of plastic (SQ) that is allowed to make 3,900 helmets? 2. What is the standard materials cost allowed ( SQSP) to make 3,900 helmets? 3. What is the materials spending variance? 4. What are the materials price variance and the materials quantity variance? Note: For requirements 3 and 4, indicate 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. Do not round intermediate calculations. Exercise 10-8 (Algo) Direct Materials and Direct Labor Variances [LO10-1, L010-2] Dawson Toys, Limited, produces a toy called the Maze with the following standards: Direct materials: 7 microns per toy at $0.33 per micron Direct labor: 1.2 hours per toy at $6.80 per hour During July, the company produced 4,600 Maze toys. The toy's production data for the month are as follows: Direct materials. 72,000 microns were purchased at a cost of $0.31 per micron. 31,750 of these microns were still in inventory at the end of the month. Direct labor: 5,820 direct labor-hours were worked at a cost of $42,486. Required: 1. Compute the following variances for July: Note: Indicate 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. Do not round intermediate calculations. Round final answer to the nearest whole dollar amount. a. The materials price and quantity variances. b. The labor rate and efficiency variances
