There was a #200%# increase pencils.

The formula for percent change is:

#p = (N - O)/O * 100%# where #p# is the percent change, #N# is the new value and #O# is the old value.

For this problem #O# is known to be 75 pencils and #N# is known to be 225 pencils, so substituting:

#p = (225 - 75)/75 * 100%#

#p = 150/75 * 100%#

#p = 2 * 100%#

#p = 200%#
