Given the following information, compute the materials price variance and the materials quantity variance. For each variance, state whether it is favorable or unfavorable. Show your calculations. 

Standard quantity per unit of output = 5 pounds 

Standard price per pound = $1.00

Total actual cost of materials purchased = $2,310

The actual quantity of materials purchased = 2,200 pounds

The actual quantity of materials used = 2,100 pounds 

Actual output = 410 units
