The percent increase #=12%.#

The percent change (increase) involves finding the difference between the initial value and final value (cost).

Initial cost = $2.50

Final cost = $2.80

Change in cost = #2.80 - 2.50 = 0.3#

The percentage increase # = # (change in value)/initial value #xx 100#

#=0.3/2.50 xx 100#

#=12%# increase in cost.
