It is Thanksgiving Eve and I am cooking tomorrow. I have just figured out how long I need to cook my nearly 10-pound turkey breast based on my recipe for a 6-pound turkey breast. (I’d ordered what was advertised as a 4- to 6-pound turkey breast; what was put in my arms as a 9.75-pound one. Panic has been slowly building.) Algebra was never my forte, so I hope my calculations are correct. For that matter, I hope algebra is the type of math I needed to use to figure this out. It has been decades, after all, since I sat in a math class.
