Answer:

There was a 20% increase

Explanation:

The formula for the change in values over a period of time is:

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

Where:

#p# is the percentage change - what we are solving for in this problem.
#N# is the New value - #60# for this problem.
#O# is the Old value - #50# for this problem.

Substituting and calculating #p# gives:

#p = (60 - 50)/50 xx 100#

#p = 10/50 xx 100#

#p = 1000/50#

#p = 20#
