Well, we know from the bar graph that only 25% of the shoppers returned on Day 2, and 75% didn't come back at all that week. Of the 25% who returned on Day 2, 19% came back on Day 3. So the percent who showed up on Day 1 and returned on Day 3 would be 19% of the 25% who returned on Day 2, or (.19)(.25.) Let's round that 19% up to 20% and find (.20)(.25) = .05, or about 5%. (I can't access the pulldown bar, so I don't know how the answer is depicted, but whatever it is, it should be close to 5%.) _________________ Veritas Prep | GMAT Instructor Veritas Prep Reviews Save$100 off any live Veritas Prep GMAT Course

For the second question, let's say there were 10 shoppers there on Day 1. We'll say that the item in question costs $1, so if all 10 bought the item, they'd have paid a total of$10.

We know that 60% purchased a separate item, so 6 of the 10 purchased a substitute item. We also know that those who purchased a different item paid 30% more, so rather than $1, they'd have paid$1.30. If 6 people paid $1.30 each, they'd have spent a total of 6*1.30 = 7.80. So (total amount spent on substitute items)/(total amount that would have been spent with no sub) = 7.80/10 = 78%. _________________ Veritas Prep | GMAT Instructor Veritas Prep Reviews Save$100 off any live Veritas Prep GMAT Course
