Moby Middle School's bowling team has three bowlers. One member scored 157 and another scored 161. The average score must be at least 165 for the team to win. Write and solve an inequality to show how many points the third bowler must score for the team to win. Graph the solution. Explain your answer.

Step-by-step explanation:

How do you find an average? Add the values then divide by how many values you added. Set up your equation with the given values, remember tho that 165 is the average, not one of the values.

157 + 161 + _____ = 165

--------------------------- Put an "x" in the blank space and replace the = with >_

3. Use greater than or equal because the problem says "at

least"

Now solve:

318 + x

----------- >- 165 Simplify

3

318 + x >- 495 Multiply by 3

× >- 177 Subtract 318. (Apologies, >- is greater than or equal)
