Let's call the score of the third game x. To find the average between 160 and 170, we can set up the following compound inequality:
160 ≤ (150 + 175 + x)/3 ≤ 170
First, let's simplify the middle expression:
325 + x ≤ 510
Now, solve for x:
x ≤ 510 - 325
x ≤ 185
So, Molly would need to score a third game with a value of x less than or equal to 185 to have an average between 160 and 170.
Molly scored 150 and 175 points on her first two rounds of Candy Crush. Write and solve a compound inequality to find the possible values for a third game that would give her an average between 160 and 170.
