You must be working with a text that's at least 14 years out of date. The stock market changed from fractions to decimals in 1997.

To calculate the amount of increase per share, we need to find the difference between the initial price and the final price of the stock.

First, let's convert the mixed fractions to improper fractions for easier calculations:

Initial price: 29 3/8 can be written as (29 * 8 + 3)/8 = 235/8
Final price: 31 2/8 can be written as (31 * 8 + 2)/8 = 250/8

Next, subtract the initial price from the final price to find the increase:

250/8 - 235/8 = (250 - 235)/8 = 15/8

Therefore, the amount of increase per share is 15/8 or 1 7/8.
