See a solution process below:

The formula for calculating the percent change in a value between two points in time is:

#p = (N - O)/O * 100#

Where:

#p# is the percent change - what we are solving for in this problem.

#N# is the New Value - 62.10 in this problem.

#O# is the Old Value - 53.84 in this problem.

Substituting and solving for #p# gives:

#p = (62.10 - 53.84)/53.84 * 100#

#p = (8.26)/53.84 * 100#

#p = 826/53.84#

#p = 15# rounded to the nearest integer.

The increase for Dow Jones Industrial Average on March 15, 1933 was approximately 15%
