1-15 Gina Fox has started her own company, Foxy Shirts, which
manufactures imprinted shirts for special occasions. Since she has
just begun this operation, she rents the equipment from a local
printing shop when necessary. The cost of using the equipment is
$350. The materials used in one shirt cost $8, and Gina can sell
these for $15 each. If Gina sells 20 shirts, what will her total
revenue be? What will her total variable cost be? How many shirts
must Gina sell to break even? What is the total revenue for
this?
