The following checkbox options contain math elements, so you may need to read them in your screen reader's "reading" or "browse" mode instead of "forms" or "focus" mode. Choice 1 of 4: C n 1 D ( C n ) C n1 D(C n ) Choice 2 of 4: C n 1 T n C n1 T n Choice 3 of 4: D ( C n ) C n D(C n )C n Choice 4 of 4: D ( C n ) D ( C n 1 ) D(C n )D(C n1 ) Grading comment: At least one of your potential answers to the previous part for P n P n should give you an equation that relates P n P n , C n 1 C n1 , and T n T n . Solve this equation and find an expression for T n T n in terms of P n P n and C n 1 C n1 .\
