Hello expert, kindly assist me with this Managerial Accounting Homework. Many thanks.

At Frigicor, the standard quantity of labor is 22 hours per refrigeration unit. The standard wage rate is $35. In July, the company produced 75 refrigeration units and incurred 2,100 labor hours at a cost of $69,000. Calculate the labor rate variance and the labor efficiency variance. Indicate whether the variances are favorable or unfavorable. (Round intermediate calculations to 2 decimal places, e.g. 14.37 and final answers to 0 decimal places, e.g. 125. Enter all variances as a positive number.)
