Harry$$s Sandwich Shop uses a process costing system for its foot$-$long sub sandwiches and carries no beginning or ending Work in Process inventories. During $2017,$ the company produced and sold $5,000$ subs and incurred the following costs:

Total Per equivalent unit

Direct material $ $5,600$ $$1\mathrm{.}12$

Direct labor $8,8001\mathrm{.}76$

Manufacturing overhead $7,2001\mathrm{.}44$

Total $$21,600$ $$4\mathrm{.}32$

The current selling price is $$6\mathrm{.}25$ per sub and the gross profit for $2017$ was $($$$6\mathrm{.}25\backslash$times $5,000)($$$4\mathrm{.}32\backslash$times $5,000)=$ $$9,650.$ Sales projections for $2018$ at the current price look flat, but the manager believes that if the sales price is reduced to $$5\mathrm{.}80,$ sales volume would increase by $600$ units. Assume that direct material and direct labor are variable costs and that manufacturing overhead costs are primarily fixed. Should Harry$$s Sandwich Shop lower the selling price?
