Tanya will make cookies for her best friend’s birthday party. The function B(n) = 12 n represents the number of cookies that Tanya will bake for the party, where “n” represents the number of dozens of cookies that she bakes. Each of the pans can hold as many as 3 dozen cookies, and she will fill a pan once she begins. She intends to bake cookies on pans that she will fill with cookie dough where. Tanya will bake as many as 14 pans of cookies. In this context what is the domain of B(n)?
Tanya actually baked all 14 pans of cookies, however only needed 9 pans of cookies of the party.

Part C
Find the number of days that the new dryers must be used before Maria
begins to save money. Round off to the nearest day.
