Zee Zee Tops Inc., manufacturer$$s plaid vinyl and chenille cartops for convertibles. These roofs sell for Rs$.200$ each and have an associated variable cost per unit of Rs$.120.$ Management fully expects next year$$s sales and NOI to drop sharply, by $20\%$ and $50\%,$ respectively, due to lack of demand $($i$.$e$.,$consumer resistance$).$ If Zee Zee$$s current level of production and sales is $112$ car tops, what is the level of fixed costs?
