Final answer:
To find the total number of games played by Sal's team, we set up a proportion with the information that Sal pitched 3 out of every 5 games and pitched 15 games in total. Solving the proportion, we find that the team played 25 games in total.
Step-by-step explanation:
The question asks us to determine the total number of games played by Sal's team based on the ratio of games he pitched. If Sal pitched 3 out of every 5 games, and he pitched a total of 15 games, we can set up a proportion to find the total number of games played by the team.
Let's denote the total number of games played by the team as x. The proportion is:
3 games pitched / 5 games = 15 games pitched / x games total
By cross-multiplying we get:
3x = 5 × 15
x = (5 × 15) / 3
x = 75 / 3
x = 25
Therefore, Sal's team played a total of 25 games.
Among the options given, the correct answer is (a) 25 games.
