Question

Last season, your favorite basketball teamwon 60 games. So far this season, yourfavorite basketball team has won 72 games.What is the percent change in the numberof games that your favorite team won fromlast season to this season?

Answer 1

In order to determine the percent change in the number of games, you first calculate the difference between the number of games won last season and current season.

current season = 70 games won

last season = 60 games won

70 - 60 = 10

next, you determine what is the associated percent of 10 games to 60 games from the last season. You proceed as follow:

(10/60)(100) = 16.66

that is, you calculate the quotient between increase of games won, the number of games won last season, and to the result you multiply by 100.

Hence, the increase in the percent of games won is of 16.66%
