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 (SQ * SP) to make 3,900 helmets? 3. What is the materials spending variance? 4. What is the materials price variance and the materials quantity variance? (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.) 1. 2. 3.
