Answer:

215

Step-by-step explanation:

To gain an average of 180 for 3 games, you would require:

180 x 3 = 540 points

this is because to find the average, you need:

average = total ÷ number of games

and so you can rearrange the equation to get the total.

We know the total of all 3 games must be 540, we just need to subtract 145 and 180 from 540 to get the 3rd game:

540 - 145 - 180 = 215

This is the minimum number of points Ben must bowl in the 3rd game to achieve an average of 180 points over 3 games.
