Answer:
60 per cent
Step-by-step explanation:
Percentage increase is "increase expressed as percentage of the old value."
Games won last year (old value) = 5
Games won this year (new value) = 8
Increase = 8 - 5 = 3
Increase expressed as % of old value = (3/5)*100 = 60%
In general
% change = 100*[(NEW - OLD)/OLD]
if sign of % change is +ve, it is an increase
if sign of % change is -ve, it is a decrease.
