The manager of the deli section of a grocery superstore has just learned that the department has 112 pounds of mayonnaise, of which 70 pounds is approaching its expiration date and must be used. To use up the mayonnaise, the manager has decided to prepare two items: a ham spread and a dell spread. Each pan of the ham spread will require 1.4 pounds of mayonnalse, and each pan of the dell spread will require 1.0 pound. The manager has received an order for 10 pans of ham spread and 8 pans of the dell spread. In addition, the manager has decided to have at least 10 pans of each spread available for sale. Both spreads will cost $3 per pan to make, but ham spread sells for $5 per pan and dell spread sells for $7 per pan. a. Determine the solution that will minimize cost.
