Problem page a medical equipment industry manufactures x-ray machines. the unit cost c (the cost in dollars to make each x-ray machine) depends on the number of machines made. if x machines are made, then the unit cost is given by the function =cx+−0.3x2126x31,935 . how many machines must be made to minimize the unit cost?

Mauro products distributes a single product, a woven basket whose selling price is $15 and whose variable expense is $12 per unit. the company’s monthly fixed expense is $4,200. required: 1. solve for the company’s break-even point in unit sales using the equation method. 2. solve for the company’s break-even point in dollar sales using the equation method and the cm ratio. (do not round intermediate calculations. round "cm ratio percent" to nearest whole percent.) 3. solve for the company’s break-even point in unit sales using the formula method. 4. solve for the company’s break-even point in dollar sales using the formula method and the cm ratio. (do not round intermediate calculations. round "cm ratio percent" to nearest whole percent.)

Swain company manufactures one product, it does not maintain any beginning or ending inventories, and its uses a standard cost system. the company's beginning balance in retained earnings is $65,000. it sells one product for $170 per unit and it generated total sales during the period of $603,500 while incurring selling and administrative expenses of $54,500. swain company does not have any variable manufacturing overhead costs and its standard cost card for its only product is as follows:
