Hello, I am looking for this help on the question. I just don't know how to get the correct numbers. Thank you in advance for your expertise.

Direct Labor Variances The following data relate to labor cost for production of 5,800 cellular telephones: Actual: 3,920 hrs. at $15.1 Standard: 3,860 hrs. at $15.4 a. Determine the direct labor rate variance, direct labor time variance, and total direct labor cost variance. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number. Rate variance Favorable v Time variance Unfavorable v Total direct labor cost variance Favorable v b. The employees may have been less-experienced or poorly trained, thereby resulting in a lower v labor rate than planned. The lower level of experience or training may have resulted in less v efficient performance. Thus, the actual time required was more v than standard
