3 In the most recent month, 145,000 items were shipped to customers using 5,600 direct labor-hours. The company incurred a total of $17,080 in variable overhead costs According to the company's standards, 0.04 direct labor-hours are required to fulfill an order for one item and the variable overhead rate is $3.10 per direct labor-hour points Required: 1. What is the standard labor-hours allowed (SH) to ship 145,000 items to customers? 2. What is the standard variable overhead cost allowed (SH x SR) to ship 145,000 items to customers? 3. What is the variable overhead spending variance? eBook4. What is the variable overhead rate variance and the variable overhead efficiency variance? Hint (For requirements 3 and 4, indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for effect (i.e., zero variance),. Input all amounts as positive values. Do no round intermediate calculations.) Print no References 1. Standard quantity of labor-hours allowed 2. Standard variable overhead cost allowed 3.
