Answer 1

Answer:

Step-by-step explanation:

Set x equal to the number of games won in 2013.

In 2014, they won 20% more than 2013 (x).  This means they won x + 0.2x, or (x(1+0.2))

In 2015, they won 50% more than 2014:

     x(1+0.2)*(1 + 0.50)

This reduces to x(1.5 + 0.3)

Games won in 2015 = 1.8 x  

Since x is games won in 2013, 1.80x means they won 80% more games since 2013.
