A Knitter's Word Problem

Noelle accidentally knit an extra pattern repeat, including increases, on the yoke of the February Lady Sweater. She now has 235 stitches, but she only needs 227. Should she:

A. Tink back 470 stitches.

B. K2tog 8 times.

C. You know you can buy sweaters at Target, right?

Next week's problem: If Knitter 1 leaves the LYS at 10:45 am with a bag of Malabrigo and Knitter 2 leaves Michael's at 11:02 with a bag of Patons Kroy, they will have a violent and virulent disagreement on Ravelry about yarn quality at what time?
