Answer:

28 games won

Step-by-step explanation:

Total number of games played by the team last year = 35

Percentage of win = 80%

Number of games won can be calculated by finding the win percentage of the total number of games played and thus can be given as :

⇒ $80\%\ of\ \textrm{Total number of games played}$

⇒ $\frac{80}{100}\times 35$

⇒ $\frac{2800}{100}$

⇒ $28$

∴ Number of games won by the team out of 35 games = 28 games
