Problem B: During December, a department completed $2,500$ units of a product that has a standard materials usage and cost of $1\mathrm{.}2$ square feet per unit at

$$0\mathrm{.}48$ per square foot. The actual material used consisted of $3,050$ square feet at an actual cost of $$2,664\mathrm{.}48.$ The actual purchase of this material amounted

o $4,500$ square feet at a total cost of $$3,931\mathrm{.}20.$

Requirement: Compute the Materials Price Variance, the Materials $($Quantity$)$ Usage Variance and the Total Materials Variance. Also indicate whether the

rariances are Favorable or Unfavorable.

$($Hint: If both Variances are Favorable or Unfavorable then you add them together and the Total Variance will be Favorable or Unfavorable.$)($If one is

Favorable and the other is Unfavorable you will subtract the $2$ and the Total Variance will take on the Favorable or Unfavorable trait of the largest

variance$)$

$($Make sure all variance amounts are positive$)$
