Ella has $40 to spend at the state fair. admission is $6 and each ride cost $3. write an inequality to find the greatest number of rides she can go on.

Inequality would be: 6 + 3x ≤ 40

Subtract 6 from both sides, 

3x ≤ 34

Divide both sides by 3, 

x ≤ 11.33

As number of rides can't be in decimal, greatest number of ride, she can go on would be nearest smaller value which is 11

In short, Your Answer is 11

Hope this helps!
