During the quarter ending June 30, the company manufactured 3,300 helmets, using 2,541 kilograms of plastic. The plastic cost the company $19,312. According to the standard cost card, each helmet should require 0.68 kilograms 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 3,300 helmets? 2. What is the standard materials cost allowed (SQ x SP) to make 3,300 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. Standard quantity of kilograms allowed 2. Standard cost allowed for actual output 3. Materials spending variance 4.
