To calculate opportunity cost, we divide the time spent on one activity by the time spent on the other activity. For Bruno, his opportunity cost of ironing a dress shirt is 10/15 or 0.67 of a tire changed. For Sasha, her opportunity cost of ironing a dress shirt is 9/15 or 0.6 of a tire changed. Therefore, the best choice is B since it correctly identifies Bruno and Sasha's opportunity costs.
