I'm having a little bit of trouble finishing the exercise, any help is appreciated.

Calculate material variances. AAA, Inc. is a manufacturer of lead crystal glasses. The standard direct materials quantity is 0.9 pound per glass at a cost of $0.45 per pound. The actual result for one month's production of 7,900 glasses was 1.3 pounds per glass, at a cost of $0.50 per pound. Calculate the direct materials cost variance and the direct materials efficiency variance
