Perfect Pet Collar Company makes custom leather pet collars. The company expects each collar to require 2.10 feet of leather and predicts leather will cost $3.70 per foot.

Without performing any calculations, determine whether the direct materials price variance will be favorable or unfavorable. 3. Without performing any calculations, determine whether the direct materials quantity variance will be favorable or unfavorable. 6. Calculate the direct materials price and quantity variances. (Round your intermediate calculations and final answers to 2 decimal places. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable.)
