Johansen 's Ice Cream Shoppe purchases fresh-baked waf .e cones from the Myra Cone Company. The cones cost Johansen \$0.28 each and are delivered once each day. Johansen 's charges customers who want their ice cream in a waffle cone an extra \$0.40. If Johansen 's runs out of waf .e cones,it estimates that it suffers a customer goodwill loss of \$0.75 for each additional customer request for a waflee cone. Unsold waffle cones are ground up and used as toppings on the frozen yogurt sold by the company. Johansen 's therefore estimates the salvage value of unsold cones at \$.06.

Determine how many waf .e cones Johansen 's should purchase each day from Myra Cone.
