Question

Quizplus · Accepted Answer

The correct answer is D because if the opportunity cost of grocery shopping had decreased, it might imply that Tammy has more time or finds it less costly in terms of what she is giving up to go shopping, which could potentially make it easier for her to use coupons, not less likely. The other options (A, B, C) provide plausible reasons for why she might not bring coupons anymore, such as fewer coupons being available, the time cost of clipping coupons being too high, or grocery prices decreasing, making coupons less necessary.
