The general model for calculating a quantity variance is:

A$)$ Actual quantity of inputs used $($Actual price $-$ Standard price$).$

B$)$ Standard price $($Actual quantity of inputs used $-$ Standard quantity allowed for output$).$

C$)($Actual quantity of inputs used $$ Actual price$)-($Standard quantity allowed for output $$ Standard price$).$

D$)$ Actual price $($Actual quantity of inputs used $-$ Standard quantity allowed for output$).$

Cassie's Candles cost formula for its supplies cost is $$1,280$ per month plus $$12$ per candle. For the month of December, the company planned for activity of $525$ candles, but the actual level of activity was $518$ candles. The actual supplies cost for the month was $$8,100.$ The spending variance for supplies cost in December would be closest to:

A$)$ $$604F$

B$)$ $$520F$

C$)$ $$520U$

D$)$ $$604U$

A favorable materials quantity variance indicates that:

A$)$ actual usage of material exceeds the standard material allowed for output.

B$)$ standard material allowed for output exceeds the actual usage of material.

C$)$ actual material price exceeds standard price.

D$)$ standard material price exceeds actual price.
