To find the total number of hours Bailey studied over the three-day period, we need to add up the number of hours she studied each day.
On day 1, she studied 1 1/2 hours.
On day 2, she studied 1/2 * 1 1/2 = 3/4 hours.
On day 3, she studied 2 1/2 * 1 1/2 = 5/2 * 3/2 = 15/4 hours.
Adding up the hours from each day, we get:
1 1/2 + 3/4 + 15/4 = 3/2 + 3/4 + 15/4 = (6 + 3 + 15)/4 = 24/4 = 6 hours.
Therefore, Bailey studied 6 hours over the three-day period.
So the answer is option B, 6 hours.
Bailey studies 3 days for her final exam in History. The first day she studied 1 1/2
hours. On day 2 she studied 1/2
as long as she did on day 1 and on day 3 she studied 2 1/2
times as long as she did on day 1. How many hours did she study over the three day period?
