Assume that Pearle Vision uses standard costs to control the materials in its made$-$to$-$order sunglasses. The standards call for four ounces of material for each pair of lenses. The standard cost per ounce of material is $$12.$ During February $2024,$ the Santa Clara location produced $6,500$ pairs of sunglasses and used $22,000$ ounces of materials. The cost of the materials during February was $$12\mathrm{.}50$ per ounce, and there were no beginning or ending inventories. Calculate the flexible budget materials cost $($i$.$e$.,$standard cost at actual volume$)$ for the completion of the $6,500$ pairs of glasses.
