Eradicate, Inc., produces and sells a line of insect repellants that are sold primarily in the summer months. Recently, the chief operating officer has become interested in possibly manufacturing a repellant, ?~?~Halt’’ that can prevent a person from being attacked by use of a ?~?~pepper’’ repellant. The appeal of this product is that it would have year-round sales and would help stabilize the income of the company.

The product, however, must be sold in a specially designed spray can that will be safe from being discharged accidentally. The product will be sold in cartons that hold 24 cans of the repellant. The sales price will be $96 per carton. The plant is now operating at only 65% of its total capacity, so no additional fixed costs will be incurred. However, a $100,000 fixed overhead charge will be allocated to the new product from the company’s present total of fixed costs.
Using the current estimates for 100,000 cartons of ?~?~Halt’’ as a standard volume, the following costs were developed for each carton, including the cost of the can:
Direct materials . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $12
Direct labor . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6
Overhead (includes allocated fixed charge) . . . . . . . . . 4
Total cost per carton . . . . . . . . . . . . . . . . . . . . . . . . . $22
Eradicate, Inc., has requested a bid from a manufacturer of specialty dispensers for a purchase price of an empty can that could be used for the new product. The specialty company offered a price of $5 for a carton of cans. If the proposal is accepted, Eradicate, Inc., estimates that direct labor and variable overhead costs would be reduced by 10% and direct materials would be reduced by 20%. 
Required:
1. Should Eradicate make or buy the special cans? 
2. What would be the maximum purchase price acceptable to Eradicate for the cans?
