A team won 8 games this year against 5 games won last year. What is the
percentage increase?​

Answer 1

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.
